Chapter 28, Problem 48A

To determine

We see a green-hot star not green but white, the reason behind this fact is to be explained.

Explanation of Solution

Introduction:

Due to the dependency on how hot they are, all stars glows in a particular color.

In the center of the visible light spectrum, the green star is radiated, which tells that the green start is emitting the few lights in all the possible colors. Because our sun emits radiation primarily in those wavelengths, the human eye has evolved to view yellow and green radiation.

Conclusion:

Hence, the green-hot star does not look green but looks white.
