Please help me follow and make sure its 100% correct ( I got the value of 2.41 , but it was incorrect)

I need help with Part E only

Use the graph in the figure (gure 1) for silicate flint glass. Figure 1 011 Index of refraction (n) What are the indices of refraction of this glass for extreme violet light of wavelength A1 = 400 11111 and for extreme red light of wavelength A2 = 700 11m 7 Answer in the order indicated. Separate your answers with a comma. 11A\" 'n/\\2 = 1.7,1.6 Previous Answers V Correct Part B What are the wavelengths of A1 = 400 um violet light and A2 = 700 um red light in this glass? Answer in the order indicated. Express your answers in nanometers separated by comma. Al', A2' = 240,430 11111 Previous Answers V PartE Use the graph in the figure (gure 1) for silicate flint glass. It a beam of white light in air strikes a sheet of this glass at 70.0 with the normal in air, what will be the angle of dispersion between the extremes of visible light in the glass? In other words, what will be the angle between extreme red and extreme violet light in the glass? Figure 1 f 1 Express your answer in degrees.
