1. Snell's Law: This law describes the relationship between the angles of incidence and refraction, and the refractive indices of the two media. It states that the ratio of the sine of the angle of incidence to the sine of the angle of refraction is equal to the ratio of the refractive indices of the two media.
2. The Law of Reflection: This law is closely related to refraction, as it describes how light bounces off a surface. It states that the angle of incidence is equal to the angle of reflection.
While the Law of Reflection is often discussed alongside refraction, it's not strictly a law of refraction.
Therefore, there's only one law of refraction: Snell's Law.
