why is it that the speed of red light is more than violet light in glass(prism)?

Asked by ashwati | 24th Feb, 2009, 03:16: PM

Expert Answer:

this is because refractive index of glass for red light is less than that for violet color.

since refractive index = c / v or v = c / refractive index

therefore less the refractive index greater the speed of light.
