A parallel beam of monochromatic light is used in a Young's double slit experiment. The slits are separated by a distance d and the screen is placed parallel to the plane of the slits. Show that if the incident beam makes an angle theta=sin^-1(lamda/(2d)) with the normal to the plane of the slits, there will be a dark fringe at the centre P_o of the pattern.

A parallel beam of monochromatic light is used in a Young's double slit experiment. The slits are separated by a distance d and the screen is placed parallel to the plane of the slits. If the incident beam makes an angle theta = sin^(-1)((lambda)/(2d)) with the normal to the plane of the slits, there will be .....at the centre P_(0) of the pattern.

A parallel beam of monochromatic light of wacelength lambda used in a Young's double slit experiment. The siits are separated by a distance d and the screen is placed parallel to the plane of the slits. The incident beam makes an angle theta=sin^(-1)((lambda)/(2d)) with the normal to the slits. A transparent sheet of refractive index 'mu' and thickness t=(lambda)/(2(mu-1)) is introduced infront of one of the slit. find the intensity at the geometrical centre.
