Red light with a wavelength of 7.50 x 10^{-7 m} m and blue light with a wavelength of 5.0 x 10^{-7 m} are beamed at a double slit with a separation of 5.00 x 10^{-6 m} m. The third order maximums for the different colours occur at different spots. What is the angle between the second order maximums?
