If a wave can be polarised, it must be

A

(a) an electromagnetic wave

B

(b) a longitudinal wave

C

(c) a progressive wave

D

(d) a stationary wave

Text Solution

Verified by Experts

The correct Answer is:
D
Transverse waves can be polarised. These include all electromagnetic waves such as light, radio waves and X-rays. On the other had longitudinal waves such as sound can not be polarised.
