What is refraction of light? Draw the diagram of refraction of light in glass slab. Write the laws of refraction.

Answer:

Refraction of light in glass slab

Refraction is the bending of a wave when it enters a medium where its speed is different. We can define it as the change in direction of a wave passing from one medium to another or from a gradual change in the medium.

Laws of refraction state that:

  • The incident ray refracted ray, and the normal to the interface of two media at the point of incidence all lie on the same plane.
  • The ratio of the sine of the angle of incidence to the sine of the angle of refraction is a constant. This is also known as Snell’s law of refraction.

sin i/sin r = constant

μ1 sin i = μ2 sin r
