Physics - Wave Optics Question with Solution | TestHub

In YDSE, angular fringe width $\theta =0.1$ and wavelength of light, $\lambda =6000\mathring{A}=6\times 10^{-7}\mathrm{m}$ If ' $d$ ' be the distance between slits then, $\theta =\frac{\lambda }{d}$ $\Rightarrow \mathrm{d}=\frac{\lambda }{\theta }=\frac{6\times 10^{-7}}{0.1}=6\times 10^{-6}=6\mu \mathrm{m}$
