Question

Which index of refraction represents the most optically dense material?
a. 1.58
b. 1.77
c. 2.42
d. 2.65

Answer 1

The relation between the refractive index and the optical density of the material is a direct relation.
This means that the more the refractive index is, the more optically dense the material is.

Based on the above, when checking the given choices, the refractive index that represents the most optically dense material would be the largest refractive index which is:
d. 2.65

Answer 2

Answer:

Explanation:It does ask for the most optically dense NOT the least.
