In Young's double-slit experiment, the separation between the slits is halved and the distance between the slits and the screen in doubled. The fringe width is

A

unchanged

B

halved

C

doubled

D

quadrupled

Text Solution

Verified by Experts

The correct Answer is:
D
The fringe width, `beta=(lambdaD)/(2d) and beta'=(lambda(2D))/(d)`
`therefore beta'=4beta`

In Young's double slit experiment, the sepcaration between the slits is halved and the distance between the slits and the screen is doubled. The fringe width is

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

In a Young's double slit experiment, the separation between the slits is d, distance between the slit and screen is D(Dgtgtd). In the interference pattern, there is a maxima exactly in front for each slit. Then the possible wavelength used in the experiment are:
