Physics - Wave Optics Question with Solution | TestHub

In the Young's double slit experiment, the intensities at two points ${\mathrm{P}}_1$ and ${\mathrm{P}}_2$ on the screen are respectively ${\mathrm{I}}_1$ and ${\mathrm{I}}_2.$ If ${\mathrm{P}}_1$ is located at the centre of a 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
