Double-Slit Interference: in a Double Slit Experiment, If the Separation

Double-slit interference: In a double slit experiment, if the separation between the two slits is 0.050 mm and the distance from the slits to a screen is 2.5 m, find the spacing between the first-order and second-order bright fringes when coherent light of wavelength 600 nm illuminates the slits.
