Question

light travels from one medium at an angel of incidence 45° to another medium making an angle og refraction 30° the ratio of refractive indices half to media is​

Answer 1

Answer:

Light refracts whenever it travels at an angle into a substance with a different refractive index (optical density). ... This change of direction is called refraction. When light enters a more dense substance (higher refractive index), it 'bends' more towards the normal line.Apr 26, 2012
