The plots of intensity versus wavelength for three black bodies at temperatures T1, T2 and T3 respectively are as shown. Their temperature are such that

A
T1>T2> T3
B
T1>T3> T2
C
T2>T3> T1
D
T3>T2> T1
Answer
T1>T3> T2
Explanation
Solution
According to Wien's law λm∝T1 and from the figure
(λm)1<(λm)3<(λm)2 therefore T1 > T3 > T2.
