Fringe width in a particular YDSE is measured to be `beta` What will be the fringe width, if wavelength of the light is doubled, separation between the slits is halved and separation between the screen and slits is tripled ?

We know that `beta=(lamdaD)/d`
Now the changed values are `lamda.=2lamda`
`d.=d/2`
`D.=3D`
`therefore` The new fringe width will be `beta.=(lamda.D.)/(d.)`
`beta.((2lamda)(3D))/((d/2))=12 (lamdaD)/d=12 beta`
The fringe width increases to 12 times of the original.
