Refraction of Light Videos
REFRACTION AT PLANE SURFACE The phenomenon of change in path of light as it goes from one medium to another is called refraction. Laws of refraction The incident ray, the refracted ray and the normal to the surface separating to two media at the point of incidence – all lie in one plane. Snell’s … Read more
