Solving a problem in physics section 34 point 97 optics

97. At the slit is normally incident parallel beam of monochromatic light. The diffraction pattern is projected onto the screen using a lens with a focal length f = 0,5 m. The width of the central bright band b = 5 cm. Determine how to change the width of the slit to the central strip fills the whole screen (if any width of the screen).
