Which of the following conditions are necessary and sufficient for total internal reflection to take place at the boundary between two optical media?
I. Light is passing from optical denser medium to optically less dense medium
II. Light is passing from optically less dense medium to optically denser medium
III. Angle of incidence is greater than a certain critical value
IV. Angle of incidence is lesser than a certain critical value
The conditions for total internal reflection include light traveling from an optically denser medium (higher refractive index) to an optically less dense medium (lower refractive index) and that the angle of incidence is greater than the critical angle.
There is an explanation video available below.
