How does the angle of deviation formed by a prism change with the increase in the angle of incidence ?
Draw a graph showing the variation in the angle of deviation with the angle of incidence at a prism surface.

Explanation

To understand how the angle of deviation formed by a prism changes with the increase in the angle of incidence, we can follow these steps:

### Step 1: Understanding the Terms
- **Angle of Incidence (I)**: The angle at which the incoming light ray strikes the prism surface.
- **Angle of Deviation (δ)**: The angle between the direction of the incoming ray and the direction of the outgoing ray after passing through the prism.

### Step 2: Observing the Behavior of Light in a Prism
When light enters a prism, it bends towards the base of the prism due to refraction. The amount of bending depends on the angle at which the light hits the prism.
