प्रश्न
Draw a ray diagram showing the path of rays of light when it enters with oblique incidence
- from air into water;
- from water into air.
उत्तर
Air is optically rarer than water.
- As water is optically denser than air, a ray of light entering from air into the water will bend towards the normal. The ray diagram showing the path of rays of light when it enters with oblique incidence from air into water;
- As water is optically denser than air, a ray of light entering from water into the air will bend away from the normal. The ray diagram showing the path of rays of light when it enters with oblique incidence from water into air;

Noor, a young student, was trying to demonstrate some properties of light in her Science project work. She kept ‘X’ inside the box (as shown in the figure) and with the help of a laser pointer made light rays pass through the holes on one side of the box. She had a small butter-paper screen to see the spots of light being cast as they emerged.
What could be the ‘X’ that she placed inside the box to make the rays behave as shown?
