If the screen is moved away from the plane of the slits in a Young's double slit experiment, then the:
If the screen is moved away from the plane of the slits in a Young's double slit experiment, then the:
angular separation of the fringes increases
angular separation of the fringes decreases
linear separation of the fringes increases
linear separation of the fringes decreases
Solution
As per YDSE, $x=\frac{\lambda \mathrm{D}}{d}$,
(where, symbols have their usual meanings)
If the screen is moving away from the slits then D increases, and hence the fringe width $(x)$ increases.
