Question

The refractive index of transparent medium is greater than one because
(a) Speed of light in vacuum < speed of light in transparent medium
(b) Speed of light in vacuum > speed of light in transparent medium
(c) Speed flight in vacuum = speed of light in transparent medium
(d) Frequency of light wave changes when it moves from rarer to denser medium

Answer 1

Answer:

(b)Speed of light in vacuum>speed of light in transparent medium.

Explanation:

As refractive index of vacuum is 1, speed of light is always greater in vacuum as compared to transparent medium. Hence, refractive index of transparent medium is always greater than one.

And that's all your answer
