Monochromatic light of wavelength 580 nm passes through a single slit and the diffraction pattern is observed on a screen. both the source and screen are far enough from the slit for fraunhofer diffraction to apply. a) if the first diffraction minima are at ±90.0∘, so the central maximum completely fills the screen, what is the width of the slit? b) for the width of the slit as calculated in part (a), what is the ratio of the intensity at θ=45.0∘ to the intensity at θ=0?
