Fringe width observed in Y.D.S.E is beta .If the frequency of the source is doubled the fringe width will become.

In an interference pattern of two wave fringe width is beta . If the frequency of source is doubled then fringe width will become :

In young's double slit experiment if the seperation between coherent sources is halved and the distance of the screen from coherent sources is doubled, then the fringe width becomes:

In young's double slit experiment, if the distance between the slits is halved and the distance between the slits and the screen is doubled, the fringe width becomes

If the frequency of the source is doubled in Young's double slit experiment, then fringe width (beta) will be –

In Young's double sit experiment two light sources when placed at a distance d apart, then Interference pattem having fringe width w. If the distance between the sources is reduced to d/3, then fringe width would be

In Young's experiments the separation of slits is made 2 times. The fringe width will become

In Young's double slit experiment the fringe width is 4mm .If the experiment is shifted to water of refractive index 4/3 the fringe width becomes (in mm)

Fringe width decrease with increase in

Two sources give interference pattern which is observed on a screen, D distance apart from the sources. The fringe width is 2 w . If the distance D is now doubled, the fringe width will
