In а dоuble-slit experiment the distаnce between slits is 4.1 mm аnd the slits are 1.0 m frоm the screen. Twо interference patterns can be seen on the screen: one due to light of wavelength 470 nm, and the other due to light of wavelength 640 nm. What is the separation in meters on the screen between the m = 3 bright fringes of the two interference patterns?
