Question
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 they are 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 :
Options
A.Both (A) and (R) are true and (R) is the correct explanation of (A)
B.Both (A) and (R) are true but (R) is not the correct explanation of (A)
C.(A) is true but (R) is false
D.(A) is false but (R) is true
Solution
Sol. [Key Concept: Both statements are true, but 'no mass' does not explain why an EM wave exerts radiation pressure.]
Assertion and reason both are correct but not related.
