An equilateral triangular prism is made of glass whose refractive index varies with length. of wave according to the relation: Picture 3.1 where the wavelength is measured in micrometers. Assume that the refractive index of air is nair = 1. Lightning of white light falls on the face of the prism at an angle of 45°, as shown in the figure. if the wavelength of red light is 0.75 μm and that of violet light is 0.39 μm, calculate: 1. the difference between the exit angles of the prism for the colors red and violet (at this difference of angles is called angular spread).
