Detailed Solution

Red colour has the maximum speed in the glass prism.
The velocity of light is given by

v = f x λ

Where

f

is the frequency and

λ

is the wavelength.
When travelling through a medium, the frequency remains unchanged, and hence, speed depends upon the wavelength of light. Red colour has the longest wavelength among VIBGYOR. So, the red colour has the maximum speed in a glass prism. Thus, the refractive index property for red will be minimum.
