Define refractive index of a transparent...

Define refractive index of a transparent medium. A ray of light passes through a triangular prism. Plot a graph showing the variation of angle of deviation with the angle of incidence.

Text Solution

Verified by Experts

Refractive Index : The ratio of the velocity of light in vacuum to the velocity of light in medium is called absolute refractive index of the medium.
Graph : The plot of angle of deviation `(delta)`. Versus angle of incidence (i) for a triangular prism is shown below.
