Question

Out of air and glass, which is optically rarer?
Give reason​

Answer 1

Answer:

Hey mate........... here's your answer

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. Case 2: When light rays travel from optically denser medium to rarer medium then they bend away from the normal.

Answer 2

Answer:

in glass the optical is rare because the density of molecules present in glass is greater than the air
