Question
The diagram below shows two parallel rays A (Orange) & B (Blue) incident from air, on air-glass boundary.
- Copy and complete the path of the rays A and B.
- How do the speeds of these rays differ in glass?
- Are the two refracted rays in glass parallel? Give a reason.

Solution
- In glass, speed of orange (A) light is more than that of blue light (B).
- No, the two refracted rays are not parallel to each other as their speeds vary in the glass.
