प्रश्न
Light of a single colour is passed through a liquid having a piece of glass suspended in it. On changing the temperature of liquid, at a particular temperature, the glass piece is not seen.
Why is the light of a single colour used ?

उत्तर
Light of a single colour is used because the refractive index of a medium (glass or liquid) is different for the light of different colours.
