Question

write down the condition for total intetnal reflection​

Answer 1

Explanation:

The conditions for total internal reflection are the the light is travelling 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.

The conditions for total internal reflection are:

1.light is travelling from an optically denser medium (higher refractive index) to an optically less dense medium (lower refractive index).

2.the angle of incidence is greater than the critical angle.
