The speed of light in a precious stone is x. If the speed of light in air is 3x108 m/s and the refractive index of the precious stone is 1.5, then what is value of x?
(1) 1x10^8 m/s (2) 1.5x10^8 m/s (3) 2x 10^8 m/s (4)3x10^8 m/s

Answer:
(3) 2x 10^8 m/s
Explanation:
Refractive index of stone is defined as the ratio of the speed of light in vacuum to the speed of light in stone.
Refractive index of stone
= Speed of light in stone/Speed of light in vacuum
hence,
1.5=(3*10^8)/x
x=2x10^8 m/s
