Question

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.

Solution

Refractive index will be different in these two cases i.e., $μ_{b l u e}$ > $μ_{r e d}$ (In glass). In the glass, the speed of red light is greater than the speed of blue light.
