Answer 1

Answer:

Two important conditions of total internal reflection are: Angel of incidence (I) should be greater than critical angel (ic). Ray should travel from denser medium to rarer medium.

Answer 2

The conditions for total internal reflection are:

• light is travelling from an optically denser medium (higher refractive index) to an optically less dense medium (lower refractive index).
• the angle of incidence is greater than the critical angle.
