Following graph shows the correct variation in intensity of heat radiations by black body and frequency at a fixed temperature

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
A, C
According to Wien's law `lambda_(m) prop (1)/(T) implies v_(m) prop T`. As the temperature of body increases, frequency corresponding to maximum energy in radiation `(v_(m))` increases.
Also area under the curve `intE_(lambda) dlambda prop int E_(v) "dv" prop T^(4)`
