Space is fill of light, inferred, ultra violet light, x-ray and more radiating from all the stars in the universe. By
definition space is only an absence of air pressure. The air we breath is under pressure by the earth's gravity.
The scientific unit is expressed in Newton's, for earth, is nine point eight to be exact equivalent to a
kilogram per square meter force ( or pound per square inch value if you like ) every cubic litre of the earth's
atmosphere.
According to Albert Einstein's General theory of relativity the earth's mass bends space. By Einstein's definition gravity is merely an area of distortion by the presence of mass in the case the earth about the equivalent of eighteen trillion metric tones shrinking space round the entire circumference. However space is a three
dimensional vanishing point depth away and behind us every direction and angle.
The mass of the earth shrinks space equally round the whole world. In fact the street of your neighborhood is bending space right
down to your own back yard as much as the streets on other side of the world is. The earth tilt shrinks space inward
onto the surface of the North poll as equally as the south poll. In fact space is compressing every micrometer of the earth's surface
together, the air we breath, us, the oceans and land masses on the surface caused by the weight of earth's own mass.
So too the nearest star to earth only eight light minutes away from us our sun. It is another example of space shrinking
round the entire circumference holding a mass together. Every galaxy right down to a microscopic speck of dust shrinks
space round them. The shrinkage of space round circumferences of every mass is a distortion of space that orbiting
bodies follow. Momentums are not high enough to escape them but fast enough not to ride all the way crashing into the
mass.
The compressed air we breath is the source of sound. Contrary to what people typically stereo type digital sound in
nature is not digital and never has been. only technology, telecommunication, radio and television station,
wireless remote controls, radar to internet technology and electronic engineering. Nature is entirely analogue.
Ripples washing onto a beach the peak of each wave travel one behind behind the other in series is a good analogy of
radio waves in the universe. The distance between each peak are wavelengths,
depending on long or short. A
cork bobbing up and down is perhaps the easiest way to visualize standing waves. The up and down bobbing show long wavelength's have very little energy while the frequently
of the bobbing of shorter wavelengths a lot more..
Music we hear is nothing more than
vibrating sources transferring the air we breath into sounds we recognize. The vibrations of musical instruments and
loud speakers act as initial standing wave sources vibrating many times per
second. We hear the air we breath accelerated creating a temporary vacuum that is instantly filled in traveling from the source like pebble ripples in a pond
radiating from the source in waves we recognize as sound and music entrainment In other words an endless maximum crest
in the case of sound air pressure and a troth of vacuum being constantly filled in traveling in waves radiation in a circle
from the sound source.
We can observe loud rock radiating from speakers popping the cone in and out in tune with the base thumping even the higher
frequencies of electric guitars vibrating the cone vigorously. We have to press lightly a finger on the cone to feel the
vibrations of quiet maladies.
Sound waves radiating from loud speakers mega phones sirens to alarms are longitudinal ripples traveling one after
the other in wave air wave fronts washing our ears we recognize as sound and meaning. Transverse
waves are different. A pendulum swing analogy accelerates, slows down to a stop to reverse direction reaccelerating that
direction to slow down again to a stop to reverse direction repeating the cycle sound waves are not.
If a pen was attached the back and forth swing draws a straight line repeated itself representation straight lines
are a reflecting of these wavelengths and example of a standing wave. If the paper is a moving conniver belt
will draw what is called a sine wave. Factures that determines this wave form include the height ( the length
of the straight line representing the amplitude of a standing sine wave ), determined by the distance of the swinging pen. The frequency of the
cycle is determined by the speed of the swing.
Park pendulum have forces the sensation we feel described as G's or centrifugal forces at work.
We experience Isaac Newtown's laws of force and motion pull and tug at us
every time we slow sown to a stop at each extreme end to reverse direction reaccelerating returning the opposite
direction repeating the cycle.
The stomach churning sensation riding pendulum motion can be exhilarating to some people every time they reverse direction.
Every time we slow down to a stop to return back, there is an equal
and opposite force changing direction resisting efforts to speed up again. It pulls back at us changing direction every time we slow down
reaccelerating the opposite direction. The frequency of the swing is determined by the weight of the person to carry the
momentum on average a cycle every few seconds.
The weight of a person can cause an out of control effect if it is just right. If a body weight is in tune the
frequency of the cycle is called resonance. The scary sensation
of feeling we are out of control going to snap the cord and fly straight on into oblivion on the next swing is Isaac Newtown's law of force and
motion at work that all bodies in motion tend to experience a force to want to travel in a straight line. We experience the the
forces of our momentum try to go straight ahead every time we approach each end of the swing.
The same straight line force apply to Rolla Coasters hitting those tight twist and curves without slowing down.
Resonance is also known when a body vibrates another. A good example is buildings vibrating in tune with
the vibrating frequency of an earthquake. The air we breath is a contributing facture adding resonance everywhere where, where planets
with no atmosphere don't have. Another example a high wind blowing down a gorge rocking and rolling a rope bridge.
The
right conditions the bridge rocks uncontrollably resonating to it's own swinging frequency kept going by wind. Engineers
have to design buildings and expansion bridges anti resonance because of the potential resonance problems present in earthquakes
and wind.
Electricity and magnetism interactions with each other is the heart of loud speakers why we find speaker voice are
magnets. The laws of electricity and magnetism
interacting with each other is the core feature how speakers produce music we recognize. Any current going though a coil
winding in a magnetic field produces forces
in the turns of the coil winding rapped round the magnet.
The electrical current reacts to the magnetic field pushing the cone outward and pulled back inwards many times per
second. The rapidly vibrating cone transfers the in and out movement to the air molecules. Tiny tweeters for the high pitch shrills of electric guitars, powerful church
organs and Scottish bag pipes are
specially designed to vibrate vigorously
up to a frequency of twenty thousand times per second.
Huge speakers reproduce the big boom of base drums and the deep base throb of double bases, designed to capture
the low rumbles of twenty times per second. This is the frequency range the best of human hearing can hear in music
and mother nature. The rest of us can only hear a limited range.
If we feel the tweeter of a loud rock song sample with our finger we can just barely feel electric guitar shrilling
vibrations. If we feel the base speaker
we can feel the vibrations of the deep base range. Twenty thousand and twenty times per second is the maximum and minimum frequency range
the best of human hearing can detect in the best hi-fi systems at minimum volume. Everybody else has to have a substantial
volume.
The technical term for the number of times per second is the frequency of vibrations. Live
as well as in loud speakers one cycle is stationary, in the case of speaker cones pull in and push out returning to stationary called a Hertz. Distance background dog bark, minimal bumps, bird calls and other noises we hear in still summer nights is a zero
decibel reference level, deci ( dear-see )
from the standard metric system prefix system for a tenth of a bell.
Zero db the maximum frequency range the best of human
hearing can hear the sounds of a quiet still summer night a pluck of an electric guitar and a boom of
a base drum at minimum volume. The unit of sound is a bell a loud rock band in the confines of a nigh club
atmosphere equal to a hundred decibels or a hundred decibels equals one Bell respectively.
If we hear twice the intensity of 0dB is only
a mere increase to a quiet rustle of leaves, as much as ten-dB up. There is not much difference in loudness between twenty,
thirty, forty dB increase in loudness a normal conversation volume to a comfortable
TV listening volume as much as sixty decibels to the average person. The best of human can notice the change in volumes.
Traffic take-off from city traffic lights is about seventy db. A rock band can drown out conversations at a eighty plus
dB. A hundred and twenty
standing
under a screaming jet engine writhen a minute of hurting our hearing.
Technically speakers and microphones are expressed as transducers. Music and voice generate a electric current in
them, in fact anything that produces electrical currents in this manor. The paper cone of speakers and diaphragms of microphones
move in
and out on a vertical plane an example of a standing wave. Another analogy of a standing wave is a bouncy spring. Springs in many machines (
inside the rocker covers of car engines for example ) stretch and compress many time per second. The revolution of a
cooling fan circling in a complete circle of an idling car engine can be as much as two to three thousand times per minute ( RPM revolutions per minute ).
When we hear sound we are hearing a longitudinal waveform molecules in the air we breath radiating from the
source in waves.
We have frequent low air pressure and the high pressure peaks many times per second traveling at the speed of sound.
There are many frequencies present in sound particularly music deep booms and rumbles of twenty hertz ( base drum's and double bases for example )
and up to twenty kilohertz ( high pitch electric guitars, powerful
church origins and Scottish bagpipe music or the real world the shrill of jet engine revs, sports whistles and bird song
) most of us can't hear only half the sound story. All this is individually heard as different loudness from individual to individual
even when at the same sound stereo volume level;.
The unit
is a measure of the
noise we hear in a still night 0 decibels barely obvious to us but to most neighborhood pets and animals can hear a lot more
frequencies at the same loudness in the seemingly deserted quietness of the silent neighborhood. It is the equivalent of
individuals able to hear the entire human frequency range at a barely minim volume. In effect our hearing is a volume control system
protecting our hearing from low and high air pressures we hear
in an average Coffey shop atmosphere.
The deep base rumbling of double base and base drums, at 70db doesn't hurt us as much as the tingling sensation we feel in our
ears the high pitch shrills of electric guitars at the same intensity. The energy of the treble range is more powerfully
than the base range at the same volume. To match the treble range has be be louder.
Light is also an oscillating energy. Light particles called photons oscillate in a similar longitudinal front as
as the air on earth. The earth's ozone layer dampens the very high ultra violet light ( UV rays ) to much lower frequencies. Another example is the
sixty hertz frequency of the mains. Alternating Current power supply. It is made up of trillions of the negatively charge particles of the atom
called electrons all resonating back and forth as one in a transverse sine wave form.
The actual voltage does not move because it's only alternating swing between positive and negative at the ends of open live wires.
The negative surge repels electrons one direction and the positive surge attracts them back sixty times in a second.
We can observe how the frequency is to fast for us to observe. The mains lighting for example resonates from minimum to maximum brightness
the corresponding sixty Hertz frequency , far to fast for us to observe the frequency so we see the oscillations as a steady light.
Mathematics tells us the reciprocal of the frequency is one divide the frequency value. For example the math's
tells us sixtieth second or decimal 0 point 0 with endless sixes of a second or sixteen millimeters long wavelength increments every second.
The same math's on twentieth second ( giving decimal 0 point 0 five of a second or fifty millimeter long wavelength )
one cycle of twenty hertz respectively.
Correspondingly the same math's with twenty kilohertz, The mains example the alternating
current sixteen millimeter increments every sixtieth second .( An electric current is
renowned for traveling close to light speed at that ).
Every musical instrument has a basic fundamental frequency containing a supplementary seven other frequencies in every note. These other
seven are
called harmonics that modulate the fundamental into a distorted characteristic waveform of a particular note. With out harmonics we would hear only the fundamental
of each note of each instrument that will sound very muffled indeed.
Stereo hi-fidelity systems are deigned to reproduce the twenty kilohertz frequencies between twenty
Hertz without drawing out
one or the other at a minimal volume. The nature of music whether live or radiating from a speaker harmonics are independent
of volume. A lot are bellow the threshold most us can't hear at low volumes. The best of human hearing can hear all the fundamental and harmonics the same volume in perfect hi-fidelity
surround sound even at minimal volume.
Base wavelengths are notoriously long. If sound travels it is the long wavelength's. The thumping base is often heard at
very faraway distances. Some of the base thumping can be as much as a couple of meters long. In comparison some of the
treble can be as short as a few centimeters distances lengthening both base and treble wave lengths which is why only
base thumping can be heard at distance.
The treble wavelengths are absorbed by by being stretched by distance, wooden furniture and walls specially if they
are cavity walls. Wooden cabinets offer excellent base at the cost of the treble range. Cavities are notorious for
resonating to the base range at the cost of the treble range. The worst thing with wooden cavity walls can resonate with the base range.
Most of the time we are hearing the walls amplifying it.. Solid concrete and steel walls deflect sound ideal sound proof
construction.
We are all familiar with emergency vehicle sirens approaching from a distance and pass us. We are hearing the high
frequency treble range constantly compressing shorter as the vehicle constantly approaches and final passing us. As the
vehicle travels past the wavelength constantly stretches longer the further the vehicle travels away. called the Doppler
effect. It is the nearest thing to Albert Einstein's theory of relativity as every body will hear the siren at the
different pitch when at different distance at the same time. The pitch heard by different distances is only relative.
The visual aspects the light we see is a tiny part of a cosmic radiation made of particles called photons waving in transverse
waves similar to sound waves. The rest of the frequency range we don't see the cosmic radiation as long as a kilometer ( Radio waves )
and short as a few thousand millionth of millimeter ( or GHz frequencies a thousand million
the heat and pressure of the sun ) called Gama Rays.
Isaac Newton discovered the clear light we see ( white light ) is made up of the exact colors of rainbow. What we see as red we are seeing the individual photon particle
jiggle back and forth the longest light wavelength our eyes can see at a very high frequency ( a few million MHz mega for a million
to be exact ). The cold colors we see are even higher blue the shortest a few
million GHz. ( Giga a thousand million ) while the rest of the radiation in the cosmos and on earth we can't see.
Equivalent to sound hot and warm colors are the base ranges and blues the treble. If we could hear the
frequencies of the warm colors we would hear base rumbling. And so with the cold colors we would hear high pitch
whistling. If we recap hot and warm colors we see equivalent to base ranges we hear and the cold colors as equivalent
to the treble range. Thus the red hues of the rainbow are low frequency light we see in it and the blues and greens the
high frequency light.
The earth's atmosphere stretches the high frequencies we can't see and compresses the wavelengths
we also can't see into the blue wavelength we can see which is why we see blue sky. We observe the suns white light at an angle in
the curvature of the earth during the transitions between night and day, as long red, orange and yellow wavelengths. Operating on
the same principle applies to paintings in artwork, all paint colors to vegetation.
Our eyes can detect the millions of shades of color. The mixing of colors in nature obeys
the same laws as mixing paint. In other words the
wavelength of the visible part of the cosmic radiation. We can see the effect by primary Red, Green and Blue.( RGB ) clear plastic
cellophane sheets.
Over laying the colors produces different colors how modern TV and video the old tube and modem windscreen LCD and Plasma TV
screens work with just with missing these three colors.
Wavelength's longer than red is invisible inferred only inferred camas can see.
They can see the heat radiating from a freshly solidified lava path that is still hot in the pitch blackness of a dark night that
would otherwise be just a black body radiation to our naked eyes converted in the camera electronics into light we see on
screen . Likewise anything with a beating heart produces the same inferred heat rays these cameras will see.
Wavelength's any longer are radio control and our entertainment remote control devices. If we had superman eyes we
would see reminiscent to a water wave flash every time we change a TV channel
The
next lowest is the radio and television broadcast transmission, telecommunication and radar including digital. These
signals are basically a fundamental longitudinal wave enveloping the complex information carried piggy back. Receivers pick up the fundamentals
filtering out it out the rest of the electronics processing the rest of the information. This includes cell phone, textting and wi-fi
internet hot spots.
Digital signals are the same processes both audio and visual only a pause between each electric shot increments where each live
shot traveling the same direction carrying the information. The purse between each shot makes the frequency of the digital signal.
The carrier wave is a fixed frequency, where the information processed by the appliance electronic designed to read and processes.
The absolute longest comic radiation wavelength is believed to be the remains of the so called big bang that has supposed to have created our
universe about a kilometer long. The old dinosaur analogue
Amplitude Modulation ( AM ) radio receivers pick these up. Tuning out of station any 1960's AM radio receiver will recorded an occasional, pop, crackle,
hiss called white static noise or visually on an old AM TV receiver a white flash or sparkle or two in the constant white noise
static. These occasional pops and crackles is believe to by only 1 percent of the white noise we hear.
On the other end of the visible spectrum if a frequency is higher than blue the wavelength we see disappears as we commonly
refer to ultra violet light
( UV a purple blue color ) rays that tans our skin. In effect a percentage of the electromagnetic radiation is compressed to UV
wavelengths. Some animals can see it. Unlike our visual world their world t is a violet color cast.
Any higher are X-rays hospitals use to examine skeletons. Frequencies higher still are a maximum called gamma rays. The higher
frequency the more powerful the energy Gamma rays the maximum of the universe can offer. Standard DVD red beam players are now to low in frequency for today's
acceptable high
definition fidelity standards. Blue ray prayers use a much lower power but higher frequency laser ray reading blue ray discs.
High powered red rays are low powered low frequency energy. A low powered blue ray has more energy than a high powered
red ray. This is why blue ray is a lower power drain on electronic power supplies with and better visual fidelity than standard DVD red ray players.
