If the atmosphere were 50 times thicker than it is now, what color would the sun appear?

Question

A. blue-violet
B. orange-green
C. red-orange
D. green-blue
E. none of the above

Answer 1

Black for I'd be dead if the atmosphere is that thick!

Serious Answer: IMO, it would not be "C". Because as the density changes, so does the sizeand quantity of the particles that get suspended in the atmosphere. So the absorption and scattering will change and the resultant color would not be the same. I have no idea what that would be, the blue-violet looks more probable.

Answer 2

C. By virtue of Rayleigh scattering, shorter wavelengths get scattered by the atmosphere and small dust particles most effectively. This means that when you look at the scattered light only, the sky is blue. Conversely, as the shorter wavelengths get filtered from the sun, it will appear to be of a color consistent with longer wavelengths, namely, red. The simple experiment to answer this question is wait until a time of day when the rays of the sun pass through the most atmosphere. This will be when it is most tangent to the surface of the earth. What color does the sun look at sunset and sunrise? Red.

Answer 3

I would imagine the same as it appears now. There is little absorption in the atmosphere (in the visible spectrum) so I would imagine it would stay the same. C

Answer 4

Red-Orange, I'm positive

Answer 5

It would definitely have to be C,

Answer 6

C.
