In Young's double slit experiment, the distance of $\mathrm{n}^{\text {th }}$ dark band from the central bright band in term of bandwidth ' $\beta$ ' is
$\mathrm{n} \beta$
$(n-1) \beta$
$(\mathrm{n}-0.5) \beta$
$(\mathrm{n}+0.5) \beta$
Solution
Distance of $\mathrm{n}^{\text {th }}$ dark band from the central bright band $=\left(\mathrm{n}-\frac{1}{2}\right) \beta$
