- 1Rarer medium to a denser medium at any angle
- 2Denser medium to a rarer medium with an angle of incidence less than the critical angle
- 3Denser medium to a rarer medium with an angle of incidence greater than the critical angle✓
- 4Rarer medium to a denser medium with an angle of incidence equal to the critical angle
