Question

what is amplitude and frequency ​

Answer 1

For waves, these variables have the same basic meaning. ... Amplitude—distance between the resting position and the maximum displacement of the wave. Frequency—number of waves passing by a specific point per second. Period—time it takes for one wave cycle to complete.

Answer 2

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.
