Electromagnetic Waves · EM waves
Given below are two statements : one is labelled as Assertion (A) : and the other is labelled as Reason (R).
Assertion (A) : The electromagnetic wave exerts pressure on the surface on which it is allowed to fall.
Reason (R) : There is no mass associated with the electromagnetic waves.
In the light of the above statements, choose the correct answer from the options given below :
- (1)Both (A) and (R) are true and (R) is the correct explanation of (A)
- (2)Both (A) and (R) are true but (R) is not the correct explanation of (A)
- (3)(A) is true but (R) is false
- (4)(A) is false but (R) is true
