Refraction through prism










                                The angle between the
                             incident ray and emergent ray
                            is called the angle of deviation.







                   angle of deviation depend           minimum deviation through a
                     on:angle of incidence.                                                    Violet has
                                                      prism is that angle of incidence         maximum
                  refracting angle of the prism.           (i) is equal to angle of            deviation.

                       R.I of the material
                   wavelength of the light ray.
