A blackened sheet of glass has 4 close parallel slits scratched in it, which allow light to pass through and form an image on a distant screen. If each slit has a width of 2.00 um and the separation (distance between centers) of adjacent slits is6.00 um determine the following. (a) The angular width of the central maximum of the diffraction pattern from an individual slit. (b) The angles at which the interference intensity maxima occur within the central diffraction maximum. (c) The angle of the first interference minimum and the angular width of the central interference maximum. You must use a phasor approach to determine this, showing your method clearly. (d) Draw a detailed, labelled, sketch of the full intensity pattern within the central diffraction maximum, as a function of the sine of the angle.
