Question

The refractive indices of three media are given below

Medium A B C

Refractive index 1.65 1.71 1.47

A ray of light is travelling from A to B and another ray is travelling from B to C. In which case

i) The refracted Ray bans toward the normal

ii) Speed of light will be more ?​
plz
give me the answer

Answer 1

Answer:

both are yes

Explanation:

Answer 2

Answer:

i) In the first case, the ray will bend towards normal, as it is moving from a medium with lower refractive index to one with higher refractive index.

ii) We know, that light travels faster in a medium with lesser refractive index. So, speed of light will be most in C, then A and then B.
