(a) Describe any two characteristic features which distinguish interference and diffraction phenomenon. Derive the expression for the intensity at a point of the interference pattern in Young.s double slit experiment. (b) In the diffraction due to a simple slit experiment, the aperture of the slit is 3 mm. If monochromatic of wavelength 620 nm is incident normally on the slit, calculate the separation between the first order minima and the third order maxima on one side of the screen. The distance between the slit and the screen is 1.5 m.
