Q. 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: Speed of light in vacuum > speed of light in tansparent medium
