These question consists of two statements each printed as Assertion and Reason. While answering these question you are required to choose any one of the following five responses.
Assertion: Blue star is at high temperature than red star.
Reason: Wein's displacement law states that
`Talpha(1/lambda_(m))`

A

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

B

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

C

If the assertion is true but the reason is false.

D

If both assertion and reason are false.

Text Solution

Verified by Experts

The correct Answer is:
A
From Wien's displacement law , temperature `(T) prop 1//lambda_(m)` ( where ` lambda_(m)` is the maximum wavelength). Thus temperature of a body is inversely proportional to the wavelength and red star has maximum wavelength , therefore blue star is at higher temperature then red star .
