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

Answer: (d) Glycerine

The refractive index is the ratio of the sine of the angle of incidence to the sine of the angle of refraction. Refractive index is defined as the bending of light rays while the light ray enters from one medium to another. It is denoted by the letter n.

n = sin i/sin r

Refractive indices of

  • Water – 1.33
  • Kerosene – 1.44
  • Mustard oil – 1.46
  • Glycerine – 1.47

Hence Glycerine is optically dense hence ray of light bends more with glycerine.
