Question

what is frequency and amplitude​

Answer 1

Amplitude is an important parameter of waves and is the maximum displacement of points on a wave. Stated another way, amplitude is the vertical distance between a peak or a valley and the equilibrium point. Frequency is the number of wave cycles passing a point per unit time.

Answer 2

Answer :

Frequency is the number of wave per unit time

Amplitude is the height of crest or depth of trough

Formulas related to frequency are as follows :

Frequency = velocity / wave length

Frequency = velocity × wave number

Frequency = 1/time period
