Question

What is scattering ? Explian Raman Scattering.

Answer 1

Scattering is nothing but a physical process through which some kind of radiation like light, sound and moving particles deviate from a rectilinear trajectory by some paths becuase of the non-uniformities in the medium through which they pass.

Sometimes when light encounters molecules in the air, an inelastic way of scattering will take place.

Such inelastic scattering is known as Raman scattering. Raman scattering depends upon the polarizability of molecules or particles.
