Which of the following is not correct?

A

A wave is a vibrating disturbance by which enegry is transmitted.

B

The speed of a wave depends on the type of wave and the neture of the medium through which the wave is traveling (for example, air water, or vaccum).

C

Wave from repeats itself at regular intervals.

D

Waves having different wavelengths and frequencies will also have different wave amplitudes.

Text Solution

Verified by Experts

The correct Answer is:
D
They can have same amplitude as it is the vertical distance from the centre line of a waves to the peak or trough.
