Question
State one advantage of using a total reflecting prism as a reflector in place of plane mirror.
Answer in Brief
Solution
The benefit of utilising a whole reflecting prism as a reflector rather than a plane mirror is that the brightness of the picture is significantly higher and stays constant even after extended use. When it comes to a flat mirror, the brightness steadily drops as the silvering on the mirror ages and gets rough.
