Question

why sky was blue ???????

Answer 1

When the sun’s light reaches the Earth’s atmosphere, it is scattered by the tiny nitrogen and oxygen molecules present in the air. 

Sunlight is made up of a spectrum of different colours that look white when we see them all mixed together, so when it is scattered, or refracted, we see different colours. 

Colours with shorter wavelengths, violet and blue, are scattered the most, so more of the blue light is scattered towards our eyes than other colours.

'So why isn’t the sky a violet colour?' you may ask. This is because our eyes are much more sensitive to the colour blue.

The reason we can’t see stars during the day is because the blue light that gives the sky its colour is much brighter.

The sky also tends to fades to pale as its nears the horizon, because the light from the horizon has had further to travel through the air and so has been scattered more.

>The atmospheric molecules scatter blue light of shorter wavelength more strongly than the red light of longer wavelength. When this scattered light reaches our eyes,it contains blue light in larger proportion. That is why the sky appears to be BLUE. .
