Statement-1 : In Young’s double slit experiment, the fringes become indistinct if one of the slits is covered with cellophane paper. Statement-2 : The cellophane paper decreases the wavelength of light.

In Young's experiment with one source and two slits, one of the slits is covered with black paper. Then

Assertion (A) : Young's double slit experiment can be performed using a source of white light. Reason (R ) : The wavelength of red light is less than wavelength of other colors in white light.

In Young's interference expriment with one source and two slits, one slit is covered with a cellophane of sheet which absorbs half the intensity. Then

Assertion (A) : Interference pattern is made by using blue light instead of red light, the fringes becomes narrower. Reason (R ) : In Young's double slit experiment, fringe width is given by the relation beta = (lambda D)/(d)

Assertion: if a glass slab is placed in front of one of the slits, then fringe with will decreases. Reason: Glass slab with produce an additional path difference.
