You are given water, mustard oil, glycerine and kerosene. In which of these media, a ray of light incident obliquely at same angle would bend the most?
(a) Kerosene
(b) Water
(c) Mustard oil
(d) Glycerine
Refractive index for water, mustard oil, glycerine and kerosene are: µw?=1.33 µm?=1.47 µg?=1.473 µk?=1.44 Since refractive index of glycerine is highest, ray bends the most in case of glycerine.
