Answer 1

When light passes through a material medium, the loosely bound electrons start vibrating under the effect of oscillating electric field of the electromagnetic weaves. In other words, we have oscillating electric dipoles due to passage of light in a material medium.

The frequency of oscillating dipoles is the same as that of incident light. The phase of these oscillations depends on the difference between incident and natural frequency of atomic electron.
