Physics - Wave Optics Question with Solution | TestHub

In the YDSE arrangement shown here, the intensity on the screen due to slit-2 is four times that of slit-1. If resultant intensity at the position of central maxima$O$is$I$, the resultant intensity at point P, where the phase difference between two waves coming from two slits is${\text{cos}}^{-1}\left(\frac{1}{4}\right)$is
