The plots of intensity versus wavelength for three black bodies at temperatures `T_(1),T_(2)` and `T_(3)` respectively are shown in Their temperatures are shown in How their temperatures are related ?
.

A

`T_(2)gtT_(3)gtT_(1)`

B

`T_(3)gtT_(2)gtT_(1)`

C

`T_(1)gtT_(2)gtT_(3)`

D

`T_(1)gtT_(3)gtT_(2)`

Text Solution

Verified by Experts

The correct Answer is:
D
As per Wien's displacement law `lamda_(m)`T = constant (b)
`thereforelamda_(m)prop1/T`
From the figure, we find that `lamda_(2)gtlamda_(3)gtlamda_(1)`
`lamda_(1)" is minimum"" "thereforeT_(1)" is maximum"`
`lamda_(2)" is maximum"" "thereforeT_(2)" is minimum"`
`thereforeT_(1)gtT_(3)gtT_(2)`
