Why the sky is blue​

Answer 1

$\huge\bold\red{Answer:-}$

It day time, when the sky appear cloudy, it appears blue in colour because the molecule of air present in atmosphere scatter blue colour of light the most. This is because, the blue colour has minimum wavelength and have maximum frequency than the red component. The blue component travel faster and reach the atmosphere. So, that's why the sky look bluer due to scattering in day time.

When a white light (from sun) enters the earth's atmosphere, it gets scattered away due to the atmospheric particles. Since, blue colour has the minimum wavelength, so blue colour scatters the most and thus the sky appears blue.
