Correct option:-

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

Answered by aggarwalreyansh43

Answer:

Refractive index of medium is inversely proportional to speed of light in the medium. 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.

Hence, correct answer is b)
