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-1 is true, Statement-2 is false.

A Young's double slit experiment uses a monochromatic source. The shape of the interference fringes formed on a screen is.....

hyperbola

circle

straight line

parabola

instead of interference diffraction appears.

fringe pattern gets more and more sharp.

angular distance between fringes increased.

fringe pattern gets less and less sharp.

instead of interference, diffraction appears

fringe pattern gets more and more sharp

angular distance between fringes increased.

fringe pattern gets less and less sharp.
