Light of wavelength 480nm falls normally onfour slits. Each slit is 2μm wide and isseperated from the next slit by 6μm.
(a) Find the angle from the center to the first point of zero intensity of the singleslit diffraction pattern on a distant screen.
(b) find the angles of any bright interference maxima that lie inside the central diffraction maximum.
(c) find the angular spread between the central inteference maximum and the firstinterference minimum on either side of it.
(d) Sketch the intensity as afunction of angle.
