Assertion : Sound waves cannot propagate...

Assertion `:` Sound waves cannot propagate through vacuum but light waves can.
Reason`:` Sound waves cannot be polarised but light waves can.

A

both, Assertion and Reason are true and Reason is the correct explanation of the Assertion.

B

both, Assertion and Reason are true but Reason is not a correct explanation of the Assertion.

C

Assertion is true but the Reason is false.

D

both,Assertion and Reason are false.

Text Solution

Verified by Experts

The correct Answer is:
b
Here, both Assertion and reason are true but reason is not correct explanation of assertion. Sound waves cannot propagate through vacuum because sound waves are mechanical waves. Light waves can propagate through vacuum, because light waves are electromagnetic waves.
