Question

define amplitude and frequency of the wave.

Answer 1

amplitude is the maximum displacement of wave from mean position

frequency is the no. of ossillations in per unit time

Answer 2

Hi !!! here is your answer.....☺️

The amplitude, a, of a wave is the distance from the centre line (or the still position) to the top of a crest or to the bottom of a trough. 

The frequency, f, of a wave is the number of waves passing a point in a certain time. We normally use a time of one second, so this gives frequency the unit hertz (Hz), since one hertz is equal to one wave per second.
