What is refraction of light? Show by ray diagram how light bends when it travels from rare to denser medium and from denser to rare medium. Define the refractive index of a medium. What are its different formulae?
Refraction of Light: Refraction is the bending of light as it passes from one medium to another due to a change in its speed. When light travels from a medium of one optical density to another, its speed changes, causing the light to bend. This bending of light is called refraction. The amount of bending … Read more
