The refractive index of a medium is dependent (to some extent) upon the frequency of light passing through, with the highest frequencies having the highest values of n. For example, in ordinary glass the refractive index for violet light is about one percent greater than that for red light.

Which light has most refractive index?

diamond, has the highest refractive index among the following. 2) Relative refractive index , where the ratio is taken between the speed of light in two mediums other than vacuum.

Which has higher refractive index red or violet?

Violet light refracts slightly more than red light. ... Violet light slows down even more than red light, so it is refracted at a slightly greater angle. The refractive index of red light in glass is 1.513. The refractive index of violet light is 1.532.
