The blue sky

It was so awful capturing a blue sky. The sky is blue because of presence of molecules which scatter blue lights because of the sun. when we look toward the sky at sunset we see red and orange colours because the blue light has been scattered. I learnt that the first attempt to explain the colours of the sky was done by Tyndall in 1859 and is called Tyndall effect. it was learnt that when light passes through a clear fluid holding particles in suspension, the shorter blue wavelength are scattered more strongly than red. This can be demonstrated by shinning a beam of white light through tank of water with milk or mixed with soap. Creations can never cease to amaze men.
