Question

what is the formula to find out the refractive index?​

Answer 1

Answer:

good morning

n=c/v

have a good

day

Answer 2

Answer:

HELLO SISTER,

HERE'S YOUR ANSWER.

=> It can be find as the ratio of Sine of Incident angle(i) to the Sine of Refracted angle(r).

n = Sin i/Sin r

=> It can be also find as the ratio of Velocity of light in one medium(c) to the Velocity of light in another medium(v).

n = c/v

HOPE IT HELPS YOU. :)
