Question

bserver.

(c) (i) State two factors on which the angle of deviation produced by a prism depends.

(ii) What should be the angle of incidence for a ray of light which suffers minimum

deviation of of 360 through an equilateral prism ?.
​

Answer 1

What do you understand by refraction of light?

Solution:

The change in the direction of the path of light, when it passes from one transparent

medium to another transparent medium, is called refraction of light.

Question: 2

Draw diagrams to show the refraction of light from (i) air to glass, (ii) glass to air. In

each diagram, label the incident ray, refracted ray, the angle of incidence (i) and the

angle of refraction (r).

Solution:

(i) Refraction of light from air to glass

(ii) Refraction of light from glass to air.
