The plots of intensity versus wavelength for three black bodies at temperatures `T_(1),T_(2)` and `T_(3)` respecttively are shown in fig. Their temperatures are such that :

Options

A. `T_(1)gtT_(2)gtT_(3)`
B. `T_(2)gtT_(3)gtT_(1)`
C. `T_(1)gtT_(3)gtT_(2)`
D. `T_(3)gtT_(2)gtT_(1)`.

Answer

C

Explanation

By Wein.s displacement law
`lamda_(m)prop(1)/(T)`.
Since `lamda_(m_(1))ltlamda_(m_(3))ltlamda_(m_(2))." ":.T_(1)gtT_(3)gtT_(2)`.
correct choice is (c ).
