White light is incident from air onto a triangular prism at a 55.0º angle with respect to the normal. The prism has an index of refraction of 1.45 for red light and 1.50 for violet light and the apex angle of the prism is 60º. Take nair=1.00 for all wavelengths.a) What is the angular separation (dispersion angle) of the two ends of the visible spectrum while in the prism?
b) What is the angular separation (dispersion angle) of the two ends of the visible spectrum upon exiting the prism?
