Question

the refractive index of a diamond is 2.42 and that of glass is 1.52. How much faster does a light travel in glass than in diamond

Answer 1

c = speed of light in air/vacuum.

(Speed of light in glass)/(Speed of light in diamond)

= (c/1.51)/(c/2.42)

= (2.42/1.51)

= 1.602.

Light travels 1.602 times faster in glass than in diamond.
