Physics Class 10th Lecture on Speed of light in a Medium

In this video Tahir Pervaz explains how Speed of light in a medium changes, when it moves from one medium to another. The amount of refraction is determined by the angle of incidence and the index of refraction. Snell’s Law can be used to calculate the angle of refraction. When the angle of incidence exceeds the critical angle it will result in total internal reflection.
