A long narrow aperture of width 200 μm is used to diffract monochromatic plane waves of wavelength 514 nm. A diffraction pattern is observed on a screen parallel to the slit and 4.00 m from it. The maximum intensity at the central bright fringe is 1.25 × 10^-6 W/m². Determine the expected intensity on the screen where the angle of diffraction θ is 1.5°.
