Question

Total internal reflecting mirrors are preferred over plane mirrors because

Answer 1

Total internal reflection:

1. Total internal reflection, in physics, is the complete reflection of a ray of light from the surrounding surfaces back into a medium such as water or glass.
2. The phenomenon occurs when the angle of incidence exceeds a certain limiting angle known as the critical angle.

Total internal reflecting mirrors are preferred over plane mirrors because

1. There is no significant loss of energy in total internal reflection.
2. The reflected ray contains all of the energy of the incident light wave, resulting in a brighter image; however, some energy is absorbed inside the plane mirror, resulting in energy loss.
