How do you verify experimentally that the angle of refraction is more than angle of incidencewhen light rays travel from denser to rarer medium. |

Answer» tion: For this we will do following experiment- Take a glass slab PASS a ray of light through it OBSERVE the light at the boundary of the both of medium from rarer to denser it will BEND towards NORMAL forming an angle known as angle of incidence .After all passing through denser medium that will be glass slab it will move away from normal forming an angle known as angle of refraction.Measure both the angles.We will observe that the angle of refraction is more than angle of incidence as it bends away from normal so it is obvious the angle will be complementary while as the first one is SUPPLEMENTARY as it bends towards normal. |
