-
Refractive index (μ): The ratio of the speed of light in air to the speed of light in the medium is called the refractive index of that medium.
CALCULATION:
Given that:
Refractive index of glass (μ) = 1.5
Speed of light in air (c) = 3 × 108 m/s
Since μ = c/v
So the speed of light in glass (v) =
Hence option 1 is correct.
