Very complex question? The index of refraction for violet light in silica flint glass is 1.65….?

The index of refraction for violet light in silica flint glass is 1.65 and that for red light is 1.62. What is the angle of deviation for the red ray passing through a prism of apex angle 58.2 degrees if the angle of incidence is 46 degrees?

What is the angular dispersion of visible light with the same angle of incidence?
