${ \huge{ \underline{ \bf{ \red{Answer}}}}}$

• The reason lies in the fact, while the speed of light is constant in vaccum And in medium. It depends the wavelength of light when it passes through a medium.
• When light passes through a medium, each colour selects it's least time path and we have refraction of different colours to different extents. This results in separations of colors when white light enters into any denser medium.
• it has been experimentally found that refractive index decreases with an increase in wavelength. if we compare the wavelength of seven colours in VIBGYOR red colour has longest wavelength and voilet has shortest wavelength
• When white light passes through the prism it will undergo refraction at two inclined surfaces. Since the refractive index of red is low hence it suffers low deviation. Whereas voilet get more deviation.
• Hence different colours undergo different deviations as they pass through prism. so, we can observe dispersion.
