Solving a problem in physics section 51 point 70 optics

70. At the slit width of 0.2 mm is normally incident monochromatic light with a wavelength of 0.5 microns. The screen, which is observed diffraction pattern is parallel to the slit at a distance of 1 m. Determine the distance between the first diffraction minima, located on either side of the central Fraunhofer maximum.
