Question

what is frequency and amplitude​

Answer 1

Frequency is the number of wave cycles passing a point per unit time.

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.

hope this helps you❤

Answer 2

Number of cycles or oscillations per unit time is known as frequency. It's SI unit is Hz and represented by nu.

the maximum position on the other side of mean value is known as amplitude. It's SI unit is m.
