Question

if c and C1 are the velocities of light in vacuum and in a medium respectively, then the relation of velocity of light with the refractive index of the medium will be-

OPT:- a) M = C1 ÷ c
b) M1 = c1c
c) M = c ÷ C1
d) M =C1 - C​

Answer 1

Answer:

c) M = c÷C1

Explanation:

the basic formula of refractive index says that it is the ratio of 'c' and 'v' where 'v' is the speed of light in the media

Answer 2

refractive index = (speed of light in vacuum) ÷ ( speed of light in medium)

M = c ÷ C1

Option C is the correct answer.
