Q:

A) Diffraction of light	B) Dispersion of light
C) Reflection of light	D) Refraction of light

Answer & Explanation Answer: B) Dispersion of light

Explanation:

A clear cloudless day-time sky is blue because molecules in the air dissipate blue light from the sun more than they dissipate red light. When we look towards the sun at sunset, we see red and orange hues on the grounds because the blue light has been scattered out and away from the line of sight.
