Correct Answer: Option B — Scattering of sunlight by atmospheric particles
Explanation:
The sky appears blue because shorter blue wavelengths of sunlight are scattered more strongly by atmospheric gas molecules compared to longe...
The sky appears blue because shorter blue wavelengths of sunlight are scattered more strongly by atmospheric gas molecules compared to longer wavelengths like red through Rayleigh scattering.
