Question

why is the sky is in blue colour​

Answer 1

Answer:

The sunlight that reaches the earth’s atmosphere is scattered in all directions by the gases and dust particles present in the atmosphere.  

The blue colour is scattered more and hence the sky appears blue.

The reason for more scattering of blue colour is that the wavelength of the blue light is shorter than the other light.

So blue light is scattered in all directions by the tiny molecules of air in Earth’s atmosphere.

This is the reason sky appears blue.

Answer 2

Answer:

the sky is in blue colour

Explanation:

the sky is blue due to a phenomenon called Raleigh scattering.this scattering refers to the scattering of electromagnetic radiation by particles of a much smaller wavelength. ... These shorter wavelengths correspond to blue hues ,hence why when we look at the sky,we see it as blue.
