Why Is the Sky Blue?
Answers
Let me explain you .....
During the day time, sky appears blue. This is because the size of the particles in the atmosphere is smaller than the wavelength of visible light, so they are more effective in scattering the light of shorter wavelengths ( blue end of spectrum ) .
When sun light passes through the atmosphere, the fine particles scattering blue colour more strongly then red. The scattered blue light enters our eye. Hence, the sky appears blue.
It should be noted that the sky appears black to the passengers flying at high altitude because scattering of the flight is not prominent at such height due to absence of particles.
I hope this helps u dear friend.

Here, the main reason for blue sky is the scattering of the light
---------------------------------------
when the earth gets the light from the sun, then the molecules in the air scatter the blue light and red light is not scattered because, the red colour is not acceptable by the molecules of air.
we see the less blue colour in the sunset or the sunrise time because, that time sun doesn't provide a proper light to the earth and that's the reason in sunset time sky is red and in morning sky is blue.
we know that, sun emits the white light, but when the sun emits the white light, then some particles are sent in the space and some particles come to the earth with the voilet and blue colour.
In the all properties of light, Dispersion is the property of light by which the light is scattered
