What is meant by scattering of light ?

Explanation

Scattering of light is the phenomenon to throw light in verious random direction. Light is
secattered when if falls on various types of suspended particles in its path. The colour of the
scattered light depends on the size of the scattering particles in the atmophere.
- The larger particles on the size of the scattering particles in the atmosphere scatter the
light of longer wevelengths due and to which the secattered light appears white.
- The extremely minute particles such as air molecules in the atmophere
scatter mainly blue light present in the white sunlight.
Colour of the sky appears blue. The molecules of air and other fine particles in the
atmosphere have a size amaller then the wevelength of visible light . So these particles
scatter more effectively the light rays of shorter wevelength at the end then light of
longer wevelength at the red. end . When the scattered blue light inters our eyes, it gives us
the feeling of a blue sky.
Colour of the sun appears red at sunrise. The sun at sunrise ans sunset is very
near to the horizon, and near the horizon most of the blue light of shorter weve-lengths is
scattered away by the particles in the atmosphere . Therefore, the light that reaches our
eyes is of longer wavelengths that in the gives rise to the raddish appearance of the sun.
