What is a total reflecting prism? State three actions that it can produce. Draw a diagram to show one such action of the total reflecting prism.

A prism having an angle of 90° between its two refracting surfaces and the other two angles each equal to 45°, is called a total reflecting prism. The light incident normally on any of its faces, suffers total internal reflection inside the prism. Due to this behavior, a total reflecting prism is used to produce the following three actions:
(a) To deviate a ray of light through 90°,
(b) To deviate a ray of light through 180°, and
(c) To erect the inverted image without producing a deviation in its path.
It is an erecting prism which is used to erect the inverted image without producing a deviation in its path
