Question:-
Define refractive index?
Answer
In optics, the refractive index of a material is a dimensionless number that describes how fast light travels through the material. It is defined as n={\frac {c}{v}}, where c is the speed of light in vacuum and v is the phase velocity of light in the medium.
Question:-
What is the meaning of that refractive index of diamond is 2.42?
Explanation:
The refractive index of diamond is 2.42. This means that the speed of light in diamond will reduce by a factor of 2.42 as compared to its speed in air. In other words, the speed of light in diamond is 1/2.42 times the speed of light in vacuum.
