For a light ray to undergo total internal reflection ($i =$ angle of incidence,$i_c =$ critical angle):
- Alight travels from denser to rarer medium and $i < i_c$.
- Blight travels from rarer to denser medium and $i < i_c$.
- Clight travels from denser to rarer medium and $i > i_c$.
- Dlight travels from rarer to denser medium and $i > i_c$.
