If a wave can be polarised, it must be

A

(a) an electromagnetic wave

B

(b) a longitudinal wave

C

(c) a sound wave

D

(d) a transverse wave

Text Solution

Verified by Experts

The correct Answer is:
D
Only transverse wave (inclusive of light wave, electromagnetic wave and others) can be polarised Longitudinal wave (such as sound wave) and stationary wave can not be polarised.
