In a double-slit experiment, the distance between slits is 5 mm and the slits are 1 m from the screen. Two interference patterns can be seen on the screen: one due to light of wavelength 480 nm, and the other due to light of wavelength 600 nm. What is the separation on the screen between the third-order bright fringes of two interference patterns?
