Assertion (A) : In interfrence pattern intensity of successive fringes due to achromatic light is not same
Reason (R ) : In interferance, only redistribution of energy takes place

Show that maximum intensity in interference pattern is four times the intensity due to each slit. Hence show that interference involves only redistribution of energy.

Show that maximum intensity in interfernce is four times the intensity due to each slit. Hence show that interfernce involves only redistribution of energy.

Assertion (A) : No interfrence pattern is detected when two coherent sources are very closer to each other. (i.e separation almost zero) Reason (R ) : The fringe width is inversely proportional to the distance between the two slits

Assertion (A) : No interfrence pattern is detected when two coherent sources are very closer to each other. (i.e separation almost zero) Reason (R ) : The fringe width is inversely proportional to the distance between the two slits

Assertion (A) : No interfrence pattern is detected when two coherent sources are very closer to each other. (i.e separation almost zero) Reason (R ) : The fringe width is inversely proportional to the distance between the two slits

Assertion (A) : The maximum intensity in interference pattern is four times the intensity in interference pattern is four times the intensity due to each slit of equal width. Reason (R ) : Intensity is directly proportinal to square of amplitude.

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 (A) : We cannot observe diffraction pattern from a wide slit illuminated by monochromatic light Reason (R ) : In diffraction pattern, all the bright bands arenot of the same intensity.

Assertion (A): Fringes of interference pattern produced by blue light is narrower than that produced by red light. Reason (R): In Young's double slit experiment, fringe width = 2lamda//d
