Question

Write 2 conditions required for the internal reflection

Answer 1

Answer:The conditions for total internal reflection are: the light is travelling from an optically denser medium (higher refractive index) to an optically rarer medium (lower refractive index) and that the angle of incidence is greater than the critical angle.

Please mark me BRAINLIEST

Explanation:

Answer 2

hey mate the two conditions are

1. angle of reflection must be greater than the critical angle
2. light ray should travel from denser to rarer medium.

hope this helps
