Incident ray on one of the face (AB) of a prism and emergent ray from the face AC are given are given in figure Q.13. Complete the ray & diagram.

AB & AC are refracting surfaces and BC is the reflecting surface. The incident ray strikes the surface AB. As the ray travels from air(rarer) to glass(denser), the ray bends towards the normal N₁ & strikes surface BC. At BC, the ray gets reflected due to total internal reflection and strikes side AC. At AC, the ray travels from glass to air, therefore the ray moves away from the normal.
