why do different colours of light white light bend through different angles with respect to the incident beam of light

Solution

Different colours of white light have different wavelengths and thus different speeds in the same medium. The colour with longest wavelength and maximum speed (red) gets deviated the least whereas colour with shortest wavelength and minimum speed(violet) gets deviated the most.

How speed of different light colour affect refraction or bending when change in medium for red colour it bend very little and violet colour bend very more when passes through prism so how bending works for different light colour?
