Question

Why is sky blue in colour . Explain it briefly.

Answer 1

1) The molecules of air and other fine particles in the atmosphere have size smaller than the wavelength of the visible light.

2) When sunlight passes through the atmosphere, the fine particles in air scatter the blue colour (shorter wavelengths) more strongly than red.

3) The scattered blue light enters our eyes and the sky looks blue.

Hope it helps you...

Answer 2

HELLO DEAR FRIEND

HERE IS THE BRIEFLY EXPLAINED ANSWER ==>

The scattering of sunlight due to the air molecules in the atmosphere causes the sky to appear blue. Shorter wavelength (Blue colour) is scattered more compared to longer wavelength (Red colour). The scattered blue light enters our eyes. thus sky appears blue.
