Physics - Wave Optics Question with Solution | TestHub

Young's double slit experiment is performed using monochromatic light of wavelength $\lambda$. The separation between the slits is $\mathrm{d}=50\lambda$ and the distance between the screen and the slits is $\mathrm{D}=1000\lambda$. If ${\mathrm{I}}_0$ is the intensity of each interfering beam, the intensity at the point on the screen directly in front of one of the slits is
