The refractive index of diamond is 2.42. What is the meaning of this statement?
Answer
We know that
Refractive index of the medium = Speed of light in vacuum or air / Speed of light of the medium
Given
Refractive index of diamond = 2.42
Hence,
2.42 = Speed of light in vacuum or air / Speed of light in diamond
Hence, refractive index of diamond is 2.42 means that
the ratio of the Speed of light in vacuum or air to the Speed of light in diamond is 2.42.
