Assertion (A): Sound waves cannot travel in a vacuum but light can travel in a vacuum.
Reason (R): Sound waves are longitudinal waves and they cannot be polarised but electromagnetic waves are transverse and they can be polarised.
- Both A and R are true and R is the correct explanation of A.
- Both A and R are true but R is not the correct explanation of A.
- A is true but R is false.
- A is false but R is true.
Answer
(B) Both A and R are true but R is not the correct explanation of A.
