The refractive index of prism material differs from colour to colour and angle of deviation ‘δ’ a light ray undergoing refraction through a prism depends on its refractive index. Thus, angle deviation is different for different colours of light.

Why is the value of angle of deviation for a ray of light undergoing refraction through a glass prism for different colours of light?
