Question

intensity at the central maxima (o) in a young's double slit experiment is Io. If the distance OP equals 1/3rd of the fringe width of the pattern , show that the intensity at a point would be I0/4. in the experiment on diffraction due to single slit show that I) The intensity of diffraction fringes decreases as the order n increases ii) angular width of the central maximum is twice that of the firdt order secondary maximum
