Nearly monochromatic coherent light waves leave two rectangular slits in phase and at an angle of θ = 22.0° with the normal. When the light reaches a distant screen, the waves from the center of one slit are 344° out of phase with the waves from the center of the other slit, and the waves from the top of either slit are 172° out of phase with the waves from the bottom of that slit. (a) How is the center-to-center distance between the slits related to the width of either slit? (b) Calculate the intensity at the screen for θ = 22.0° if the intensity at θ = 0° is 0.234 W/m2 .
