Question

light is travelling from air to light . what should be the angle of incidence so that angle of incidence=angle of refraction​

Answer 1

Answer:

When light rays travel from air into glass or from air into water, it bends towards normal. ... Case 2: When light rays travel from optically denser medium to rarer medium then they bend away from the normal. In this case the angle of refraction is greater than angle of incidence........................
