Physics - Wave Optics Question with Solution | TestHub

In Young's double-slit experiment, the intensities at two points${\mathrm{P}}_1$and${\mathrm{P}}_2$on the screen are${\mathrm{I}}_1$and${\mathrm{I}}_2$respectively. If${\mathrm{P}}_1$is located at the central bright fringe and${\mathrm{P}}_2$is located at a distance equal to a quarter of fringe width from${\mathrm{P}}_1$, then$\frac{{\mathrm{I}}_1}{{\mathrm{I}}_2}$is
