Atmospheric Scattering Problem

jcdenton89
Hello, just need some guidance - I hope my logic is correct!

Homework Statement

So I have a scenario where the Earth's atmosphere, instead of scattering blue light from the sun, actually scatters green light based on Rayleigh scattering.

I know that the sky will therefore appear green, but how will the sun appear?

I reasoned the sun will be magenta using the normal situation on Earth.

Homework Equations

Not an equation type problem but relies on the Rayleigh scattering principle.

The Attempt at a Solution

The sun appears yellow/red (toward sunsets) even though its true color is closer to white because the sun's high frequency light (violet/blue) is scattered in the atmosphere by oxygen and nitrogen molecules. Yellows and reds are low frequency, long wavelength, and are able to penetrate the atmosphere without scattering. During sunsets, the angle of sunlight is very shallow and must go through more atmosphere and undergo more scattering. Much less blue light is transmitted and the low end of the color spectrum is dominant - so we see red/orange sunsets

If in a similar situation, green light were to be scattered, then wouldn't green light be much less dominant in the color spectrum? So by removing Green from the additive primary colors, we lose yellow (normal perceived sun color) and cyan as well. The blue and red frequency light will be able to penetrate the atmosphere, mix, and result in magenta with a scattered green sky as the background.

What do you think? I was toying between a yellow or magenta sun...but i think magenta seems a good option.
