How do you Measure the Refractive Index?The law of refraction states that:The incident ray, the refracted ray and the normal all lie in the same plane.The ratio of the sine of the angle of incidence, i to the sine of the angle of refraction, r is a cons…

What do you mean by Total Internal Reflection?The inside surface of water can act like a perfect mirror as shown in Figure. This happens when the light rays strike the surface of the water in such a way that it reflects back into the water.The light rays…
