Fig. 2 illustrates a setup showing how an incident light is refracted and reflected by a rectangular prism and a plane mirror.

Here are two precautions to obtain good results in this experiment: Ensure the optical pins are fixed vertically to mark the positions accurately. Avoid parallax error when viewing the pins by keeping the eye directly in line with the pins.
