Refraction is the bending of light at the surface of separation, which takes when it passes from one optical medium to another optical medium with different optical densities.

Draw the diagram of refraction of light in the glass slab
A ray of light passes from glass into air. The angle of refraction will be:
(a) equal to the angle of incidence
(b) greater than the angle of incidence
(c) smaller than the angle of incidence
(d) 45°
How is the angle of emergence related to the angle of incidence when prism is in the position of minimum deviation? Illustrate your answer with help of a labelled diagram using an equilateral prism?
-
- the angle of refraction and
- the angle of deviation for the ray?
How does the deviation produced by a prism depend on the refraction index of its material.
Which colour of light travels fastest in any medium except air?
Name one main factor on which the direction of bending of a ray of light depends.
State the factors on which the angle of deviation depends.
Complete the ray diagram showing its emergence into the air after passing through the prism.
Which colour of white light travels fastest in any medium except air?
