Question

In a Young's double slit experiment, the angular width of fringe formed on a distant screen is $0.1$ $radian$ . Find the distance between the two slits, if wavelength of light used is $6000\,\mathop A\limits^o $....$\mu m$

Answer

In $YDSE$

$\theta = \frac{\lambda }{d} = 0.1 \Rightarrow d = \frac{\lambda }{\theta } \Rightarrow d = 6\,\mu m$
