Question
Refractive index is a property of ____.
- A medium
- A pair of mediums
- Infinitely many mediums
- A substance
Hint:
The property known as the refractive index defines how the medium affects the speed of light passing through it.
The correct answer is: A pair of mediums
The refractive index is the property of a pair of mediums.
- The refractive index is compared with two mediums that are rarer and denser medium.
- It is the ratio of the speed of light in medium 1 and medium 2.
- So the refractive index is a material property of both the mediums.
