Question
Which of the following has the highest refractive index?
- Water
- Air
- Glass
- All of the above
Hint:
The denser the medium the more the refractive index.
The correct answer is: Glass
The correct option is c) Glass.
The refractive index of denser mediums is high. As we know glass is denser than both air and water, therefore the refractive index of water is more. The refractive index of glass is 1.52 and of water is 1.33
