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:
C
According to Wien's law `lambda_(m) alpha (1)/(T) implies v_(m) alpha T`. As the temperature of body increases, frequency corresponding to maximum energy in radiation `(v_(m))` increases. Also area under the curve
`intE_(v) dv alpha T^(4)`
