उत्तर
Two characteristic features distinguishing the diffraction pattern from the interference fringes obtained in Young’s double slit experiment are as follows:
1. The interference fringes may or may not be of the same width whereas the fringes of diffraction pattern are always of varying width.
2. In interference the bright fringes are of same intensity whereas in diffraction pattern the intensity falls as we go to successive maxima away from the centre, on either side.
