Question

The ratio of the speed of light in a vacuum to its speed in a given substance is:

• A. Reflection index
• B. Medullary index
• C. Refractive index
• D. Reflux index

Hint:

Refractive index comparisons help match glass fragments to their source in forensic cases.

Answer 1

The Correct Option is C

The refractive index measures how much light bends or slows down as it enters a medium. It is crucial in forensic glass analysis to compare refractive properties of glass fragments at crime scenes.
