A ray of white light travelling through the air strikes the surface of a sheet of crown glass at an

angle of incidence of 38.0°. The refractive indices for crown glass for red and violet light are 1.513and 1.532 respectively.a)Which is refracted more, the red or the violet light?b)What is the angle of refraction for the red light?c) What is the angle of refraction for the violet light?d) What is the angle of dispersion? (Angle between the directions in which both lights emerge)​
