Question

(a) A ray of light goes from Medium 1 to Medium 2. The angle made by the light ray with the
normal at the point of incidence in Medium 2 is greater than the angle made by it in Medium 1. On
the basis of the given information, answer the following questions: (2+3)
i. Which of the two media has a higher optical density? Justify your answer.
ii. When the optical density of the medium increases, how does the refractive index and the speed
of light vary?
(b) A narrow beam „PQ‟ of white light is passing through a glass prism „ABC‟ as shown in the
diagram given below:

(i) Trace it on your answer sheet. Show the path of emergent beam on the screen DE and mark the
acronym.
(ii) Name the phenomenon and write its cause.
