Question

why Is sky blue? please tell answer​

Answer 1

${\huge{\boxed{\mathcal{\pink{ANSWER  :-}}}}}$

the sky is blue due to a phenomenon called Raleigh scattering. This scattering refers to the scattering of electromagnetic radiation (of which light is a form) by particles of a much smaller wavelength. Sunlight is scattered by the particles of the atmosphere, and what comes through down to earth is called diffuse sky radiation, and though only about 1/3rd of light is scattered, the smallest wavelengths of light tend to scatter easier. These shorter wavelengths correspond to blue hues, hence why when we look at the sky, we see it as blue. At sunset and sunrise, the angle at which sunlight enters the atmosphere is significantly changed, and most of the blue and green (shorter) wavelengths of light are scattered even before reaching the lower atmosphere, so we see more of the orange and red colours in the sky.

Answer 2

Explanation:

Sky is blue because when the rays of sunlight coming to Earth have to face many barriers of the earth's atmosphere. Due to which the white light get scattered into 7 colours. Out of which the most scattered colours are those who have high wavelength that a Violet, Indigo and Blue. Which combines to give sky a blue colour.
