Question

Analyse from the picture and find out the substance that has the lowest refractive index. 

hintHint:

 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.
