A beam of white light is incident normal...

A beam of white light is incident normally on the surface AB of an equilateral prism ABC and emerges out of it suffering a deviation of `60^(@)`.
(a) Draw a diagram to show the path of beam till it emerges out of the prism. Mark the angles wherever necessary.
(b) What assumption have you made while drawing the diagram ?
(c) Name the phenomenon exhibited by the light beam.

### Step-by-Step Solution #### (a) Diagram of the Path of the Beam 1. **Draw the Prism**: Start by sketching an equilateral triangle to represent the prism ABC, where points A, B, and C are the vertices of the triangle. 2. **Incident Ray**: Draw a straight line representing the beam of white light incident normally on the surface AB. Since it is normal incidence, the angle of incidence (i) is 0 degrees. ...
