Question

why sky is blue in colour​

Answer 1

Explanation:

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.

Answer 2

Answer:

As sunlight of all colors are passes through air,the blue part causes charged particles to oscilate faster than does the red part.More of the sunlight entering the atmosphere is blue than violet, however,and our eyes are somewhat more sensitive to blue light than to violet light,so the sky appears blue.
