Q14 of 16 Page 26

In the experiment to trace the path of a ray light a triangular glass prism.

1. If the emergent ray makes an angle 35 with the second face of the prism , then what is the angle of emergence.


2. Can the angle of deviation be zero and why?

1. The angle of emergence


2. No, because at the second refracting surface of the prism , a ray of light moves from denser to a rarer medium, it bends away from the normal, I.e., bends towards the base of the prism.
