This physical process is skewed in people who suffer from keratoconus [keh-rah-toe-KOE-nus] or astigmatism, and it can be impacted by direction in materials with birefringence [bie-ree-FRIN-jens].
This phenomenon explains why it is easier to hear noises across a lake at nighttime rather than during the day. This physical process is skewed in people who suffer from keratoconus [keh-rah-toe-KOE-nus] or astigmatism, and it can be impacted by direction in materials with birefringence [bie-ree-FRIN-jens]. Beyond a critical angle, total internal reflection occurs instead of this wave phenomenon. Name this phenomenon quantified by Snell's Law, the bending of light as it changes from one medium to another.
