A point light source emits E.M. waves in free space. A detector, placed at a distance of $\displaystyle L \mathrm{~m}$, measures the intensity as $\displaystyle I_{\mathrm{o}}$. The detector is now shifted to another location on the same spherical surface ensuring the angle between original location and new location as $\displaystyle 45$°. The measured intensity at new location will be $\displaystyle \_\_\_\_$.
