In Young's interference experiment, a monochromatic beam of light with 1 = 500 nm passes through identical slits whose slits are 1 mm apart and each slit has a width w. If on a screen 2 m from the slit it is observed that the 4th-order main maximum interference is lost, then (a) determine the width of the slit w, and (b) determine the width of the diffraction principal envelope.
