(a) A ray of light goes from Medium 1 to Medium 2. The angle made by the light ray with thenormal at the point of incidence in Medium 2 is greater than the angle made by it in Medium 1. Onthe 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 speedof light vary?(b) A narrow beam „PQ‟ of white light is passing through a glass prism „ABC‟ as shown in thediagram given below:(i) Trace it on your answer sheet. Show the path of emergent beam on the screen DE and mark theacronym.(ii) Name the phenomenon and write its cause. |
