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

Glide: 1
AMPLITUDE
Amplitude is the height of a wave, measured in meters (m). The higher the amplitude the higher the intensity of the wave.
Glide: 2
WAVELENGTH
Wavelength is the length of one wave, measured in meters (m).
Glide: 3
RAREFACTION
Rarefactions
The part of the wave where the particles are spread out far apart is called rarefaction.
Glide: 4
COMPRESSION
Compressions
The part of the wave where the particles are compressed together is called compression.
Glide: 5
FREQUENCY
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.
