Question

In which of the following material light velocity maximum
A) glass (n=1.5)
B) water (n=1.33)
C) diamond (n=2.42)
D) rock salt (n=1.54)

Answer 1

Answer: OPTION(B) IS THE ANSWER

Explanation:

n(refractive index) =velocity of light in vaccum /velocity of light in media

SO MATERIALS WITH HIGH REFRACTIVE INDEX IS MORE DENSER AND THE VELOCITY OF LIGHT WOULD BE LEAST IN THEM SO REFRACTIVE INDEX IS INVERSLY PROPORTIONAL TO THE SPEED OF THE LIGHT.

SO THE VELOCITY OF LIGHT WILL BE MAXIMIUM IN WATER IN THE FOLLOWING OPTIONS.
