In a double-slit experiment you saw in class the distance among slits is 5.0 mm and the slits are 1.0 m from the screen. Two interference patterns can be seen on the screen, one due to light by wavelength 480 nm and the other due to light with wavelength 600 nm. What is the separation on the screen among the third-order (m = ±3) interference fringes of the two dissimilar patterns?
