Statement-1 : When temperature of a black body is doubled, energy radiated/sec/area becomes `16` times.
Statement-2 : This is per Stefan's law.

A

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

B

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

C

If Assertion is true but the Reason is false.

D

If both, Assertion and Reason are false.

Text Solution

Verified by Experts

The correct Answer is:
A
According to Stefan's Law, `E prop T^(4)` when `T` becomes twice, `E` becomes `2^(4)` times, i.e., `16 times`. Both the statements are true and statement-2 is correct expalnation of the statemetn-1.
