Electromagnetic waves (EMW) exerts pressure, called radiation pressure.
In perfect reflecting waves, p=

2I

C

In perfect absorbing waves, p=

I

C

So, Assertion is true.
EMW exert pressure on the surface because they carry energy also.
Therefore reason is also true.
Buc, Reason (R) is not a correct explanation of Assertion (A).
