5. Why do different colours deviate through different angles on passing through a prism?

Different wavelengths deviate differently in the prism because the angle of refraction for different colours having different wavelengths is different while passing through the glass prism and refractive index depends upon wavelength of light. refractive index is inversely proportional to wavelength.
