Q. $S_{1}$ And $S_{2}$ are two coherent sources. The intensity of both sources are same. If the intensity at the point of maxima is 4 $Wm^{- 2}$, the intensity of each source is
A) 1 $Wm^{- 2}$
B) 2$\ Wm^{- 2}$
C) 3$\ Wm^{- 2}$
D) 4$\ Wm^{- 2}$
Explanation
(a) At a point of maxima
$\therefore\ I_{\max} = 4I_{0} = 4\ Wm^{- 2}$
$\therefore I_{0} = 1\ Wm^{- 2}$
