The prism in the diagram is being used as a mirror. (a) Construct a ray diagram to indicate how the light entering the prism travels. Show how it reflects off the back face and also where the reflected ray leaves the prism. (b) Is point A, B, C, D, or E most likely to intercept an outgoing ray?

Applications Of Reflection Of Light
When a light ray (termed as the incident ray) hits a surface and bounces back (forms a reflected ray), the process of reflection of light has taken place.
Sign Convention for Mirrors
A mirror is made of glass that is coated with a metal amalgam on one side due to which the light ray incident on the surface undergoes reflection and not refraction.
The prism in the diagram is being used as a mirror.
(a) Construct a ray diagram to indicate how the light entering the prism travels. Show how it reflects off the back face and also where the reflected ray leaves the prism.
(b) Is point A, B, C, D, or E most likely to intercept an outgoing ray?
(c) The incoming ray hits the back left face of the prism at what angle? (in terms of the normal to the back face)
(d) A reflected ray leaves the back left face of the prism at what angle?
(e) What is the index of refraction of the prism if the ray experiences total internal reflection when it hits the back face of the prism?
