What is the ratio of velocity of red light to velocity of violet light in vaccum?

Hey there !
In other media the speed differs. That's why we have not only refraction (bending of light), but also dispersion, like in a prism.
Red light entering glass is broken less than violet light.
The amount of refraction depends on the relative speeds in the two media (vacuum and glass). We call that the breaking index
n
, where
n=
speed in vacuum/speed in glass.
Apparently the ratio for red is less than that for violet.
nred<nviolet
