Question

# Refractive indices of four media P, Q, R, S are $$1.33, 1.44, 1.52, 1.65$$ respectively. In which of these media is the speed of light maximum?

A
P
B
Q
C
R
D
S

Solution

## The correct option is A PSpeed of light ,$$v=\dfrac{c}{\mu}$$                     where $$c$$=speed of light in vacuum                      and  $$\mu$$ = refractive index of mediumHence, for maximum speed, $$\mu$$ should be minimum.Hence, speed of light will be maximum in P having minimum $$\mu$$.Answer-(A).Physics
