Write a short note on dispersion of light.
Explain the term absolute refractive index of a medium and write an expression to relate it with the speed of light in vacuum.
Draw the diagram given below and clearly show the path taken by the emergent ray.

A glass slab is placed over a page on which the word VIBGYOR is printed with each letter in its corresponding colour.

What do you understand by the deviation produced by a prism?
In the diagram below, PQ is a ray of light incident on a rectangular glass block.

Copy the diagram and complete the path of the ray of light through the glass block. In your diagram, mark the angle of incidence by letter ‘i’ and the angle of emergence by the letter ‘e’.
Complete the ray diagram showing its emergence into the air after passing through the prism.

The diagram shows the path of a ray of light through a rectangular glass block placed in a liquid of uniform density.

What should be the rate of the speed of light through the liquid to the speed through the glass so that there is no refraction of light at the boundaries of the glass block when the system is illuminated by the light of one colour?
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.
