In Young's double slit experiment shown in figure. \( S_{1} \) and \( S_{2} \) are coherent sources and \( S \) is the screen having a hole at a point \( 1.0 \mathrm{~mm} \) away from the central line. White light ( 400 to \( 700 \mathrm{~nm} \) ) is sent through the slits. Which wavelength passing through the hole has strong intensity?
(1) \( 400 \mathrm{~nm} \)
(2) \( 700 \mathrm{~nm} \)
(3) \( 500 \mathrm{~nm} \)
(4) \( 667 \mathrm{~nm} \)
