A beam of ligth consisting of two wavelength `4,800 overset@A` and `6,000 overset@A` is used to obtain interfernce fringes in a double slit experiment.The distnce between the slits is 1.8 mm and the distance of screen from the plane of slits is 1.2 m
What is the lest distance from the centre of the screen,where the brigth fringes due to both the wvelength coincide?
