Question

A black body radiates at two temperatures T1 and T2 . Such that T1<T2 . The frequency corresponding to maximum intensity is (A) less at T1  (B) more at T1  (C) equal in the two cases (D) cannot say

Tardigrade Admin · Accepted Answer

According to Wiens law, as T increases λ m decreases and vm increases. As T1<T2 Therefore, vm1<vm2

Q. A black body radiates at two temperatures $T_{1}$ and $T_{2}$ . Such that $T_{1} < T_{2}$ . The frequency corresponding to maximum intensity is

less at $T_{1}$

more at $T_{1}$

equal in the two cases

cannot say

According to Wiens law, as T increases $λ_{m}$ decreases and $v_{m}$ increases. As $T_{1} < T_{2}$ Therefore, $v_{m_{1}} < v_{m_{2}}$
