Sound Vocabulary - wavelength definition - what is amplitude, frequency, compression, Rarefactions

FREQUENCY
AMPLITUDE
WAVELENGTH
Frequency is the number of waves to pass a point every second, measured in Hertz (Hz). The frequency of audible sound ranges from 20Hz to 20,000Hz.
Amplitude is the height of a wave, measured in meters (m). The higher the amplitude the higher the intensity of the wave.
Wavelength is the length of one wave, measured in meters (m).
COMPRESSION
Compressions
Sound
RAREFACTION
Rarefactions
The part of the wave where the particles are compressed together is called compression.
The part of the wave where the particles are spread out far apart is called rarefaction.
