प्रश्न
In an experiment of finding the refractive index of glass, if blue light is replaced by the red light, how will the refractive index of glass change? Give reason in support of your answer.

उत्तर
In glass, the speed of blue light is less than that of the red light. Now, the refractive index is μ = c/v. Hence, the refractive index of glass for red light will decrease as compared to that for blue light.
