Chapter 9, Problem 9.26E

(a) Use Wien displacement law to determine the ${\lambda }_{\max }$ of the Sun if its surface temperature is $5800\text{K}$. (b) The human eye sees light most efficiently if the light has a wavelength of $5000\stackrel{\text{o}}{\alpha }\left(1\stackrel{\text{o}}{\alpha }={10}^{-10}\text{m}\right)$, which is in the green-blue portion of the spectrum. To what blackbody temperature does that correspond? (c) Compare your answers from the first two parts and comment.
