Write the conditions for total internal reflection.
(N/A) Total internal reflection occurs when the following two conditions are met:
$1$. The light must travel from a denser medium to a rarer medium.
$2$. The angle of incidence $(i)$ in the denser medium must be greater than the critical angle $(c)$ for the pair of media involved $(i > c)$.
