The plots of intensity versus wavelength...

The plots of intensity versus wavelength fro three black bodies at temperatures `T_(1),T_(2)` and `T_(3)` respectively and shown in Fig. 15.11.1. Their temperatures are such that

A

`T_1gtT_2gtT_3`

B

`T_1gtT_3gtT_2`

C

`T_2gtT_3gtT_1`

D

`T_3gtT_2gtT_1`

Text Solution

Verified by Experts

The correct Answer is:
B
According to Wien's law, `lambdaT=` constant. From the graph
`lambda_(1) lt lambda_(3) lt lambda_(2)`
`:. T_(1) gt T_(3) gt T_(2)`.
