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 constant,Refractive Index Formula: The value of this constant, for a light ray passing through a vacuum … [Read more...] about How do you Measure the Refractive Index?

What do you mean by Total Internal Reflection?
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 are said to be reflected internally. This phenomenon is known as total internal reflection. It occurs only … [Read more...] about What do you mean by Total Internal Reflection?
