Assertion : For higher temperature, the peak emission wavelength of a black body shifts to lower wavelengths.
Reason : Peak emission wavelength of a black body is proportional to the fourth power of temperature.

A

If both assertion and reason are correct and reason is a correct explanation of the assertion.

B

If both assertion and reason are correct but reason is not the correct explanation of assertion.

C

If assertion is correct but reason is incorrect.

D

If assertion is incorrect but reason is correct.

Text Solution

Verified by Experts

The correct Answer is:
C
According to Wien.s displacement law.
`lamda_m prop 1/T`
So, peak emission wavelength is inversely proportional to its absolute temperature.
