Why white light split into 7 colours when passed through prism

1.	Why white light split into 7 colours when passed through prism
Answer» HLO MATE HERE IS UR ANSWER ⭐. The speed of light is constant in vaccum for all colours , but it depends on the wave length of light when it passes through a medium. ⭐. We know that refractive index of a medium depends on wavelength of light ⭐. When white light passes through a medium , each colour selects its least time path and we have refraction of different colours to different extents. ⭐. This results in seperation of colours , producing a spectrum. ⭐. It has been experimentally found that refractive index decreases with an increase in wavelength. ⭐. In VIBGYOR , red colour has longest wavelength and voilet colour has shortest wave length . The refractive index of red is low , hence it suffers low deviation.
