Question

Which of the following has the lowest refractive index?

• A. Turpentine
• B. Benzene
• C. Water
• D. Kerosene

Hint:

Refractive index determines how much light slows down when passing through a medium.

Answer 1

The Correct Option is D

The refractive index of kerosene is lower compared to turpentine, benzene, and water, meaning light travels faster in kerosene than in the other substances. Thus, the correct answer is \( \mathbf{(D) \text{Kerosene}} \).
