Refracion of light
The phenomenon of a change in the direction of propagation of light when it passes obliquely from one transparent medium to another is called refraction of light.
For a given angle of incidence, the extent of refraction of light is different in different media.
- When the refractive index of the second medium is greater than the refractive index of the first medium, more is the bending of the refracted ray towards the normal.
- When the refractive index of the first medium is greater than the refractive index of the second medium, lesser is the bending of the ray of light away from the normal.
