Question

what do u mean by amplitude, wavelength and frequency

Answer 1

Amplitude: an important parameter of all waves. Amplitude: maximum displacement of points on a wave.
Wavelength: the distance between two successive like points on the wave.
Frequency: the number of wave cycles passing a point in a unit of time.

Answer 2

Answer :

Amplitude - the distance between mean to one of its extreme is called its amplitude.

Frequency - total no of vibrations or oscillations per second is called frequency.
