Wien's displacement law
Students often get confused between Wien's displacement law and Planck's radiation law. Although both are historically related, yet they are conceptually different. Planck's law helps determine the spectrum of a blackbody, while Wien's law determines the…

Answer to Problem 1FC

The correct option for the surface temperature of two stars is “(a) star A has the greater surface temperature”.

Explanation of Solution

Given data:

Star “A” has maximum curve at shorter wavelength than star “B”.

Explanation:

Refer to Figure 29.2 in the textbook for the electromagnetic radiation emitted by a perfect blackbody.

At high temperature, the intensity per unit length is greater, and the maximum curve is obtained at shorter wavelength. Since star “A” has the maximum curve at shorter wavelength than star “B”, the surface temperature is greater in star “A”. Therefore, option (a) is correct. Remaining options (b), (c), and (d) are incorrect.

Conclusion:

Hence, the correct option for the surface temperature of two stars is “(a) star A has the greater surface temperature”.
