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

Options

A. Both A and R are true and R is the correct explanation of 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

Answer

B

Explanation

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
