A ray of light XY passes through a right angled isosceles prism as shown alongside Figure.
(a) What is the angle through which the incident ray deviates and emerges out of the prism?
9b) Name the instrument where this action of prism is put into use.
(c) Which prism surface will behave as a mirror ?

Text Solution

Verified by Experts

The correct Answer is:
(a) Angle of deviation=the angle which the emergent ray makes with the incident ray
`XY=90^(@)`, (b) periscope, (c) the surface AB of the prism behaves as the mirror.
