In Young’s double slit experiment, show graphically how intensity of light varies with distance.
Draw: graph showing variation of intensity of light with distance in Young's double slit experiment
Must show: central bright fringe, alternate dark and bright fringes of equal intensity and fringe width, intensity on y-axis and distance / path difference on x-axis
(ii)[1.5]
In Fraunhofer diffraction, how is the angular width of the central bright fringe affected when slit separation is increased?
