Question

The refractive indices of water___ glass ___ air.

  1. <, <
  2. <, >
  3. =, <
  4. >, =

hintHint:

More the dense the medium is more will be the refractive index.

The correct answer is: <, >


    The correct answer is c) <,>.
    The refractive index of water is 1.333, the refractive index of glass is 1.52 and the refractive index of air is 1.0003.Which means the refractive index of glass is greater than both air and water. The refractive index is the lowest.
    Hence,

    The refractive indices of water < glass > air.
