The ratio of the speed of light in vacuum to that in a medium is called
The ratio of the speed of light in vacuum to that in a medium is called
Show Hint
\(n = \frac{c}{v} \geq 1\) for all media.
Updated On: Apr 24, 2026
- luminous intensity
- luminous flux
- magnification factor
- refractive index of the medium
- transparency index
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept:
Refractive index \(n = \frac{c}{v}\).
Step 2: Detailed Explanation:
By definition, the refractive index of a medium is the ratio of speed of light in vacuum to speed of light in the medium.
Step 3: Final Answer:
Refractive index of the medium.
Refractive index \(n = \frac{c}{v}\).
Step 2: Detailed Explanation:
By definition, the refractive index of a medium is the ratio of speed of light in vacuum to speed of light in the medium.
Step 3: Final Answer:
