This simulation explores the refraction of light at a plane boundary between two media with different indicies of refraction.[br][list][*]Use the sliders to change the indicies of refraction for each medium and to change the angle of incidence.[/*][*]The refracted and reflected rays are displayed. [/*][*]The relative refractive index n[sub]12[/sub] is displayed: n[sub]12[/sub] = n[sub]2[/sub] / n[sub]1[/sub][/*][/list]
