Chapter 6, Problem 1SEPP

Interpretation Introduction

Interpretation:

The approximate surface temperature of sun (in kelvin) is to be evaluated.

Concept introduction:

Wien’s law states that the relationship between the wavelength of maximum intensity $\left({\lambda }_{\max }\right)$ in blackbody radiation and the kelvin temperature of the radiating body $\left(T\right)$ is as follows:

${\lambda }_{\max }=\frac{b}{T}$

Here, $b$ is the Wien’s displacement constant $\left(2.898\times {10}^6\text{ nm}\cdot \text{K}\right)$.

The most intense emission $\left({\lambda }_{\max }\right)$ from sun occurs at $500\text{ nm}$.
