Explanation:
ray of light when it
travels from
a. a rarer to a denser medium.
b. a denser to a rarer
Answer:
When light rays travel from optically rarer medium to denser medium then they bend towards normal. In this case angle of refraction is smaller than angel of incidence.
When light rays travel from air into glass or from air into water, it bends towards normal. This is because the speed of light rays decrease while travelling from air into glass or water.
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.
When light rays travel from glass into air or from water into air they bend away from the normal. The speed of light rays increase while travelling from glass or water into air.
