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

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)
