According to Wien's displacement law λm T=b In terms of frequency, (c/vm) T=b or vm=(c/b) T Hence, the vm-T graph is a straight line as shown by curve C.

Q. Which one of the following is $v_{m} - T$ graph for perfectly black body? $v_{m}$ is the frequency of radiation with maximum intensity and $T$ is the absolute temperature.

A

B

C

D

According to Wien's displacement law
$λ_{m} T = b$
In terms of frequency, $\frac{c}{v _{m}} T = b$
or $v_{m} = \frac{c}{b} T$
Hence, the $v_{m} - T$ graph is a straight line as shown by curve $C$ .

Q. Which one of the following is vm​−T graph for perfectly black body? vm​ is the frequency of radiation with maximum intensity and T is the absolute temperature.

A

B

C

D

According to Wien's displacement law λm​T=b In terms of frequency, vm​c​T=b or vm​=bc​T Hence, the vm​−T graph is a straight line as shown by curve C.
