Question

if green light is scattered more often
than any other frequency of light what…‡
color would the sky be
at noon?

Answer 1

Basically the sky is transparent. During the daylight,though, when the Sun is above (and at noon especially), the air molecules begin scattering the light coming from the Sun. Due to the Rayleigh scattering, in view of our eye's receptors, the sky assumes that color (i.e. that frequency, or wavelength, of scattered light) which has the property of being scattered the best: which in real life is blue. If we postulate that green light is scattered more often than any other frequency of light, then the color of the sky at noon would be green.
