What are the two conditions necessary for total internal reflection to occur?

Feedback

a) Light must pass from an optically denser medium to a less optically dense medium.

b) The angle of incidence in the denser medium must be greater than the critical angle.

Question

One of the formula below is not used to calculate the value of the refractive index;

Answers

Sin r/Sin i = n

η= velocity of light in vacuum/velocity of light in the medium

n =1/sin C.

n= Real depth/Apparent depth.
