JEE Main 2026 — 5 April, Evening Shift — Question 14
Assertion (A): The electromagnetic wave exerts pressure on the surface on which they are allowed to fall.\nReason (R): There is no mass associated with the electromagnetic waves.
- Option A:
Both (A) and (R) are true and (R) is the correct explanation of (A)
- Option B:Correct
Both (A) and (R) are true but (R) is not the correct explanation of (A)
- Option C:
(A) is true but (R) is false
- Option D:
(A) is false but (R) is true
Answer: B
Step-by-step solution
Both statements are correct, but the reason (no mass) does not explain why EM waves exert pressure (which is due to momentum transfer).
