refraction is the change in direction of a wave passing from one medium to another or from a gradual change in the medium.

refractive index or index of refraction of a material is a dimensionless number that describes how fast light travels through the material. It is defined as. where c is the speed of light in vacuum and v is the phase velocity of light in the medium.

Total internal reflection when refraction reflection at critical angle and refraction takes place called TIR
