In a double-slit experiment the distance between slits is 5.22nm and the slits are 1.36m from the screen Two interference pattern can be seen on the screen one due to light with wavwlength 480nm and the other due to light with wavelength 612nm. Find the separation on the screen between the third order interference finges of the two different patterns
