The speed of light in dense flint glass...

The speed of light in dense flint glass is 3/5 of its speed in air. The refractive index of dense flint glass is

A

1.5

B

1.75

C

1.666

D

1.1

Text Solution

Verified by Experts

The correct Answer is:
C
`n = (V_(a))/(V_(d)) = (V_(a))/(3//5 V_(a)) = (5)/(3) = 1.666`.
