Answer:

Optical media are media through which electromagnetic waves pass through. Every optical medium has its own refractive index due to its different optical density.

As an electromagnetic wave moves through vacuum, it travels at a speed of 3.00 x 108 m/s (the speed of light). Once the wave hits particles at the surface of the medium, energy is absorbed and the electrons begin to vibrate. If the energy of the electromagnetic wave does not match the vibrational frequency of the electron, the energy is re-emitted in the form of an electromagnetic wave with the same frequency and speed (speed of light) through the interatomic space of the medium. This process repeats itself when this new wave hits the next particle that comes in its way. This is basically a cycle of absorption and re-emission that continues throughout the medium until the wave reaches the other ‘outer’ surface of the medium.
