Refraction of light






                                    Bending of light when it
                                   passes from one medium to
                                  another is called Refraction of
                                           light.



                                                  Laws of refraction of light
                   When light rays travel from                                 An object appears to be raised
                   optically rarer medium to   1) The incident ray, refracted ray and the   when paced under water.
                   denser medium then they   normal at the point of incidence, all lie in
                  bend towards normal & vice   the same plane, i.e. the surface/Interface.  Pool of water appears less deep
