A black body radiates heat at temperatures `T_(1)` and `T_(2) (T_(2) gt T_(1)` the frequency corresponding to maxium energy is

A

more at`T_(1)`

B

more at `T_(2)`

C

equal for `T_(1)` and `T_(2)`

D

independent of `T_(1)` and `T_(2)`

Text Solution

Verified by Experts

The correct Answer is:
b
Energy radiated by the bodies are
`E_(1)= sigmaAT_(1)^(4)` and `E_(2)=sigmaAT_(2)^(4)`
`rarr (E_(2))/(E_(1))=(T_(2))/(T_(1))^(4) gt1`
or `h v_(2) gt h v_(1) or v_(2) gt v_(2)`
thus frequency corresponding to `T_(2)` is more
