The amount that the ray of light will refract is related to the index of refraction of the medium. The index of refraction, n (no units), is defined as the ratio of the speed of light in a vacuum and the speed of light in the

ncert.nic.inLight – Reflection and Refraction 161 Let us recall these laws – (i) The angle of incidence is equal to the angle of reflection, and (ii) The incident ray, the normal to the mirror at the point of incidence and the reflected ray, all lie in the same plane. These laws of reflection are applicable to all types of reflecting surfaces
