In a Young's double slit experiment, the slits are placed $\displaystyle 0.320$ mm apart. Light of wavelength $\displaystyle \lambda=500 \mathrm{~nm}$ is incident on the slits. The total number of bright fringes that are observed in the angular range $\displaystyle -30^{\circ} \leq \theta \leq 30^{\circ}$ is :
Official answer
(4)
$\displaystyle 641$
