Answer:
Laws of refraction state that:
The incident ray refracted ray, and the normal to the interface of two media at the point of incidence all lie on the same plane. The ratio of the sine of the angle of incidence to the sine of the angle of refraction is a constant. This is also known as Snell's law of refraction.
Explanation:
Refraction is the bending of a light or sound wave, or the way the light bends when entering the eye to form an image on the retina.
The angle of incidence is the angle between the incident ray and the normal; denoted as ‘i’. The angle of refraction is the angle between the refracted ray and the normal; denoted as ‘r’. Laws of refraction state that:
