In a YDSE setup the two slits are 2 mm apart and screen is placed at distance of 2 m from slits. The slits are illuminated with bi-chromatic beam of light of wavelength 400 nm and 500 nm. The minimum distnace from central line where bright fringes of both wavelength coincide (other than central fringe) is |
