Show with the aid of a ray diagram, how a right angled isosceles prism can be used to invert the rays. (a) How sould the rays fall on the prism ?
(b) Which phenomenon is responsible for this action of prism? (c) What is the nature of the image in relation to the object ?

Explanation

To solve the problem of how a right-angled isosceles prism can be used to invert rays, we will follow these steps:

### Step 1: Understanding the Prism
A right-angled isosceles prism has two equal sides and a right angle between them. The hypotenuse acts as the entry and exit surface for light rays.

### Step 2: Drawing the Ray Diagram
1. **Draw the Prism**: Start by sketching a right-angled isosceles prism. Label the vertices as A, B, and C, where A and B are the ends of the base, and C is the apex of the right angle.
2. **Incident Ray**: Draw an incident ray approaching the prism from the left side, striking the hypotenuse (AC) at an angle. Label the point of incidence as D.
