Assertion (A) Radiation is the fatest mode of transmissin of heat
Reason (R ) : Conduction and convection require a medium for transmission of heat where as heat radiations can travel through vaccum .

A

Both A and R are correct and R is the correct explanation of A.

B

Both A and R are correct but R is not the correct explanation of A

C

A is correct and R is incorrect.

D

Both A and R are incorrect.

Text Solution

Verified by Experts

The correct Answer is:
B
Radiation is the fastest mode of transmission of heat. It does not require any medium as, it transmits heat in the form of electromagnetic waves. But conduction and convection require a material medium for transmission of heat. So, A and R are correct, but R is not the correct explanation of A.
