The index of refraction for violet light in silica flint glass is 1.66 and that for red light is 1.61. The angle of deviation for the red ray passing through a prism of apex angle 55.6 deg when the angle of incidence is 51.3 deg is 41.7deg. What is the angular dispersion of visible light with the same angle of incidence.
