Hi,
Refraction of light occurs when a ray of light travels from one medium to another .When it enters into a different medium the light bends towards the normal.
This extent of bending of light depends upon the refractive index of the medium.
Refractive index of a substance is the ratio of speed of light in vaccum to the speed of light in the given substance.
Cheers!!
