Question

Why sky in blue colour?

Answer 1

The molecules present in air scatter blue light and they don't scatter other colours with high wavelength like red much so sky appears blue

Answer 2

Heyya!


During the daytime, sunlight travels through a thin layer of atmosphere. Red and orange light are scattered the least by tiny particles because its wavelength is the longest. Violet and blue light are scattered the most by tiny particles because its wavelength is the shortest. This gives the sky its blue appearance. Violet light is not seen because our eyes are more sensitive to blue light. Hence more blue light enters our eyes.
