COMPRESSION WAVE
|
A sound wave. Is made up of compressinos and rarefactions
|
|
|
Transverse Wave
|
A light wave; includes crest, teough, wavelength, etc.
|
|
|
Vibration
|
the back and forth movement of matter. It causes sound
|
|
|
Sound
|
a form of energy that travels through matter in waves; it is caused by vibrations
|
|
|
Crest/Peak
|
It represents the compressions of a sound wave; it's the highest point of a wave.
|
|
|
Trough
|
It represents the refraction of a wave; the lowest point of a wave.
|
|
|
Wavelenghth
|
The distance from one compression or crest to the next.
|
|
|
Frequency
|
The number of vibrations that are produced in a given unit of time; it determines pitch.
|
|
|
Compression
|
Part of the sound wave where the molecules are packed close together.
|
|
|
Refraction
|
Part of the sound wave where the molecules are spread apart.
|
|
|
Sonar (sound navigation and ranging)
|
Process that uses sound waves to locate objects-Ships, Planes, Weater.
|
|
|
Echolocation
|
Process in which animals (bats) send out sound waves in order to find food.
|
|
|
Medium
|
The material that sound waves travel through (ex: air, water).
|
|
|
Pitch
|
The highness or loweness of a sound; it is determined by the frequency of a vibrating object.
