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. When is the glass piece not seen?

उत्तर
The glass piece is not seen when the refractive index of liquid becomes equal to the refractive index of glass.
