(B) When white light passes through a prism,it splits into its constituent colors due to the difference in their refractive indices in the glass medium.According to the relation $v = c/n$,where $v$ is the velocity of light in the medium,$c$ is the speed of light in a vacuum,and $n$ is the refractive index of the medium.The refractive index $n$ is inversely proportional to the wavelength $\lambda$ of the light.Red light has the longest wavelength,which results in the lowest refractive index for the glass prism.Since the refractive index is lowest for red light,its velocity $v$ is the maximum among all the colors of the visible spectrum.

In the dispersion of white light by a prism,which color of light has the maximum velocity?
