Question

Can visible light be scatter by atoms or molecules in earth's

atmosphere?

Answer 1

according to Rayleigh scattering →

Rayleigh scattering:
This happens when light waves are scattered by very tiny objects smaller than the wavelength of light. (400 nm - 700 nm). The atoms and molecules of Oxygen/Nitrogen in the atmosphere, having diameters of 0.3 nm approx, do scatter light rays. That is one of the reasons why sky appears blue usually.

Answer 2

HEY , HERE'S THE ANSWER ⏬

The atoms or molecules present in the earth atmosphere is not so large compared to the outer atmosphere so for the light to be scattered it needs large atom or molecule so that it can scattered light properly .However the smoke or dust present in the atmosphere scatters light.
