Fringe width of an interference fringe is y for the two given waves. If the frequency of the source becomes double then the fringe width have been

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

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

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

The fringe width of interference fringes for red colour is beta . The fringe width for the violet colour will be nearly :

In interference with two coherent beams of light , the fringe width is

The width of an interference fringe is 1.5 mm . What would be the width of the fringe if the separation between the slits is made twice the original value?

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 seperation between coherent sources is halved and the distance of the screen from coherent sources is doubled, then the fringe width becomes:

How does fringe width vary with wave length?
