A light ray in passing from medium A to medium B slows down.
(i) Draw a diagram to show the path of the light ray in the two media.
(ii) Name the medium which is optically denser than the other.

Explanation

To solve the question step by step, we will address both parts: drawing the diagram and identifying the optically denser medium.

### Step 1: Draw the Diagram
1. **Identify the Media**: Let's label medium A as the rarer medium and medium B as the denser medium.
2. **Draw the Incident Ray**: Start by drawing a straight line representing the incident ray coming from medium A towards the boundary of medium B.
3. **Draw the Normal Line**: At the point where the incident ray meets the boundary between the two media, draw a dashed vertical line. This line represents the normal, which is perpendicular to the surface at the point of incidence.
4. **Draw the Refracted Ray**: Since the light ray slows down when entering medium B, it bends towards the normal. Draw a line that represents the refracted ray bending towards the normal on the side of medium B.
5. **Label the Diagram**: Clearly label medium A, medium B, the incident ray, the normal line, and the refracted ray.
