A beam of laser light of wavelength 632.8 nm has a circular cross-section 2.00 mm in diameter. A rectangular aperture is to be placed in the center of the beam so that when the light falls perpendicularly on a wall 5.40 m away, the central maximum fills a rectangle 110 mm wide and 6.60 mm high. The dimensions are measured between the minima bracketing the central maximum. Find the required width and height of the aperture.
