Question
Analyse from the picture and find out the substance that has the lowest refractive index.
Hint:
The refractive index of a medium is directly proportional to its density.
The correct answer is:
When compared to mustard oil, kerosene, and glycerine, the refractive index of water has the lowest refractive index.
- The refractive index in a pair of mediums depends on the density of the second medium.
- The refraction is more in a more dense medium and in the less dense medium, the refraction will be less comparatively.
- The water has less density compared to mustard oil, kerosene, and glycerine and so its refractive index will be less comparatively.
