If a wave is going from one medium to another, then

A

frequency

B

wavelength

C

velocity

D

amplitude

Text Solution

Verified by Experts

The correct Answer is:
b., c., d.
Frequency is the property of source while velocity is the property of medium and wavelength is the property of both medium and source. So, wavelength and velocity of wave must change as the medium change, while frequency remains same. On the amplitude (and hence intency) can decrease as the medium change.
Amplitiude will either decrease or remain the same but it can never increase due to change in medium (assuming no external source is providing energy).
