The refractive index of glass is 1.5. Calculate the speed of light in glass. The speed of light in air is 3.00×108m/s.

Given,

Refractive index of glass = 1.5 Speed of light in air = 3.00×108m/s

Refractive index of glass = (speed of light in air)/(speed of light in glass) Speed of light in glass = 1.5
