Assertion : Electromagnetic waves exert ...

Assertion : Electromagnetic waves exert radiation pressure
Reason : Electromagnetic waves carry energy.

A

B

Both A and R are true and R is NOT the correct explanation of A.

C

A is true but R is false

D

A is false and R is true

Text Solution

Verified by Experts

The correct Answer is:
B

Electromagnetic radiation is composed of photons which has momentum (hv) and energy `(lambda//h)`. When photon is incident on a surface, its momentum changes which gives rise to radiation pressure So, the assertion and reason both are true but the reason does not explain the assertion
