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

Answer» Correct Answer - 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 |
