In a double slit experiment , the coherent sources are spaced 2d apart and the screen is placed a distance D from the slits. If n^("th") bright fringe is formed on the screen exactly opposite to a slit , the value of n must be -

In Young's double slit experiment, the two slits are at a distance 'd' apart. Interference pattern is observed on a screen at a distance D front the slit, if at a point on the screen, directly opposite to the slits, the first dark fringe is observed, then wave length of the wave will be

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 Po of the pattern.

In Young's double slit experiment the two slits are d distance apart. Interference pattern is observed on a screen at a distance D from the slits. A dark fringe is observed on the screen directly opposite to one of the slits. The wavelength of light is

Statement I: In Young's double-slit experiment, the two slits are at distance d apart. Interference pattern is observed on a screen at distance D from the slits. At a point on the screen which is directly opposite to one of the slits, a dark fringe is observed. Then, the wavelength of wave is proportional to the squar of distance between two slits. Statement II: For a dark fringe, intensity is zero

Statement-1: In Young's double slit experiment the two slits are at distance d apart. Interference pattern is observed on a screen at distance D from the slits. At a poit on the screen when it is directly opposite to one of the slits, a dard fringe is observed then the wavelength of wave is proportional of square of distance of two slits. Statement-2: In Young's double slit experiment, for identical slits, the intensity of a dark fringe is zero.

White light is used to illuminate the two slits in a Young's double slit experiment. The separation between the slits is b and the screen is at a distance d (gtb) from the slits. At a point on the screen directly in front of one of the slits, certain wavelength are missing. Some of these missing wavelength are
