Amplitude

The maximum displacement of sound waves from its mean position is called amplitude. its SI unit is metre (m)

Time period

A time period (denoted by 'T' ) is the time needed for one completecycle of vibration to pass in a given point. As the frequency of a wave increases, the time periodof the wave decreases. The unit for time period is 'seconds'.

Frequency

Frequency describes the number of waves that pass a fixed place in a given amount of time. ... The hertz measurement, abbreviated Hz, is the number of waves that pass by per second i.e SI unit is hertz.
