The Laws of Refraction with Examples

The Laws of Refraction

1.Incident ray, reflected ray, refracted ray and the normal of the system lie in the same plane.

2. the ratio of sini and sinr is a constant, which is known as refractive index. It is known as Snell's law

Answer 2

1= incident ray , the reflected ray and normal at the point of incidence , lie in the same place.

2= The angle of incidence in always equal to the angle of reflection.
