SOUND WAVES/HISTORY OF SOUND WAVES
PRODUCED WHEN A VIBRATION CAUSES PRESSURE VIBRATIONS IN THE MEDIUM
SOUND
iS THE HIGHNESS AND LOWNESSS OF A SOUND.
PITCH
THE DISTANCE A SOUND WAVE TRAVELS PER UNIT OF TIME AS IT PROPAGES THROUGH A MEDIUM.
SPEED OF SOUND
This produces a good deal of harmonic content and therefore a full buzzing sound.
SAWTOOTH WAVE
IT CANNOT PASS THROUGH BOUNCING REFLECTIONS THAT TRAVEL OFF A SURFACES
WAVES
FREQUENCY IS MEASURED IN CYCLES PER SECONDS OR HERTZ
FREQUENCY
IS THE MAXIMUM DISPLACEMENT OF THE MEDIUM FROM ITS REST POSITION.
AMPLITUDE
The most basic and simple waveform, a sine wave has a simple hollow sound. It does not exist in nature, but is the simplest sound to reproduce with electronics, which is why you may recognize it from warning tones and beeps.
SINE WAVE
SOUND WAVES NEEDS A MEDIUM TO TRAVEL THROUGH.
PROPAGATION OF SOUND
FREQUENCIES BELOW 20HZ
INFRASONIC WAVES
A WAVE'S WAVELENGTH INCREASES WITH INCREASING FREQUENCY
WAVELENGTH
This causes the waves to take on a bit more of the shape of a sine wave, while maintaining the sharp edges of a square wave.
TRIANGLE WAVE
THE SPEED OF A FREQUENCY IS UNAFFECTED BY REFLECTION, BUT A WAVE CAN BE FLIPPED UPSIDE DOWN.
BEHAVIOR OF WAVES
THE SPACE BETWEEN A POINT ON ONE WAVE AND THAT SAME POINT ON THE UPCOMING WAVE CYCLE.
WAVE LENGTH
WHEN A WAVELENGTH DECREASES, THE FREQUENCY INCREASES.
SPEED OF SOUND
This harmonic structure gives the square wave a little more bite to the sound. I
SQUARE WAVE
He basically came to a conclusion after taking a chisel and scrapping it against a brass plate. From there, he began to observe the pitch of the screeches that are created due to the contact of the 2 materials.

it is commonly designated by the Greek letter lambda
