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…

Explanation of Solution

Introduction:

The visible spectrum has the frequency range from 430THz to 770THz. It is the part of the electromagnetic spectrum which is visible to the human eye.

The ultraviolet region is a part of the visible spectrum. Its frequency is 1014 Hz which lies in the visible spectrum. So, when one sees a violet-hot star, one can be certain its peak intensity is in the ultraviolet region.

Conclusion:

Their frequency range lies in the visible spectrum.
