With the help of labelled ray diagram show the path followed by a narrow beam of monochromatic light when it passes through a glass prism.

Explanation

To show the path followed by a narrow beam of monochromatic light when it passes through a glass prism, we will create a labeled ray diagram. Here’s a step-by-step solution:

### Step 1: Draw the Prism
- Begin by drawing a triangular prism. The prism should have two triangular faces and three rectangular faces. Label the prism as "Glass Prism."

### Step 2: Draw the Incident Ray
- Draw a straight line representing the narrow beam of monochromatic light approaching the prism. Label this line as "Incident Ray (I)." Make sure this ray is directed towards one of the rectangular faces of the prism.
