Applications Of Reflection Of Light

When a light ray (termed as the incident ray) hits a surface and bounces back (forms a reflected ray), the process of reflection of light has taken place.

Sign Convention for Mirrors

A mirror is made of glass that is coated with a metal amalgam on one side due to which the light ray incident on the surface undergoes reflection and not refraction.

Question

Two unknown materials, A and B, have indices of refraction of
1.4 and 1.8, respectively. At what angle should you shine a light
in A so that you can have total internal reflection?
a. 90 degrees
b. 51.06 degrees
c. O degree
d. total internal reflection does not occur
