For which pair among the following, the refractive index will have the minimum and maximum value, respectively?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → Vacuum, diamond
The refractive index is minimum for the medium in which light travels fastest and maximum for the medium in which light travels slowest.
Among the given materials:
Vacuum → $n = 1$ (minimum)
Diamond → $n \approx 2.42$ (maximum)
Hence, the pair with minimum and maximum refractive index respectively is:
Answer: Vacuum, diamond
