Answer

(a) The angle through which the incident ray deviates and emerges out of the prism is the angle of deviation.

The angle of deviation = the angle which the emergent ray makes with the incident ray XY = 90°.

(b) The instrument where this action of prism is put into use is the periscope.

(c) The surface AB of the prism behaves as a mirror.
