​

Answer 1

Answer:

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- The number of waves that passes a fixed point in unit time.

Amplitude- The maximum displacement or distance moved by a point on vibrating body or wave measured from its equilibrium position.
