Assertion: Like light radiation, thermal radiations are also electromagnetic radiation.
Reason: The thermal radiations require no medium for propagation.

A

If both assertion and reason are true and the reason is the correct explanation of the assertion

B

If both assertion and reason are true but reason is not the correct explanation of the assertion

C

If assertion is true but reason is false.

D

If the assertion and reason both are false

Text Solution

Verified by Experts

The correct Answer is:
