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.

Statement-1 is true, statement-2 is true: Statement-2 is a correct explanation for statement-1

Statement-1 is true, statement-2 true, statement-2 is not a correct explanation for statement-1

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 I is True, statement II is True, Statement II is a correct explanation for Statement I.

Statement I is Ture, Statement II is Ture, Statement II is NOT a correct explanation for Statement I.

Statement I is True, Statement II is False.

Statement I is False, Statement II is True.
