Light travels slower in glass than in air because

A

a refractive index of air is less than that of glass

B

b refractive index of air is greater than that of glass

C

c density of glass is greater than that of air

D

d density of glass is less than that of air

Text Solution

Verified by Experts

The correct Answer is:
A
Speed of light depends upon the refrective index of
medium, higher the refrective index slower is the speed
of light. Hence due to higher refrective index of glass
than air light travels slower in glass medium.
