In a Young’s double slit experiment, slit width is d and light of wavelength λ. is used to observe interference pattern at a screen placed at a distance D from the plane of the slits. The fringe width is given by:
1
\(\rm \frac{\lambda D}{d}\)
2
\(\rm \frac{\lambda d}{D}\)
3
\(\rm \frac{\lambda D}{2d}\)
4
\(\rm \frac{\lambda d}{2D}\)
