A black body radiates heat at temperatures `T_(1)` and `T_(2) (T_(2) gt T_(1)` the frequency corresponding to maxium energy isA. less at `T_(1)`B. more at `T_(1)`C. equal in the two casesD. cannot say

Answer» Correct Answer - A
Acoording to wien , Law
`t_(m)prop(l)/(T^(-))rArr(C)/(v)prop(l)/(T)`
i.e `vpropT^(-)`
Since `T_(1)ltT_(2)^(-)`
therefore `V_(1)ltV_(2)`
