For some types of glass, the index of refraction varies with wavelength. A prism made of a material with n = 1.71 – 4/30 lambda_0, (lambda_0 in mu m), where lambda_0 is the wavelength in vacuum, was used to disperse white light as shown in Fig. P9. The White light is incident at an angle of 50 degree, the wavelength 0 of red light is 0.7 mu m, and that of violet light is 0.4 mu m. Determine the angular dispersion in degrees (as shown in the figure).
