Question

What is the refractive index of alcohol?

Answer 1

Refractive index:

1. Alcohol has a refractive index of 1.36.
2. The refractive index is the ratio of light's speed in a vacuum to its speed in a particular medium.
3. Refractive index can also be written as $n=\frac{C}{v}$.
4. In descriptive text, the refractive index variable is most commonly represented by the letter $n$ or $n^{\text{'}}$.
