Consider a Young's double slit experiment as shown in figure. What should be the slit separation d in terms of wavelength $\displaystyle \lambda$ such that the first minima occurs directly in front of the slit $\displaystyle \left(\mathrm{S}_1\right)$ ?
Official answer
(2)
$\displaystyle \frac{\lambda}{2(\sqrt{5}-2)}$
