The intensity \( I \) of light from an isotropic point source is determined as a function of distance \( r \) from the source. Figure \( 32-29 \) gives intensity \( I \) versus the inverse square \( r^{-2} \) of that distance. The vertical axis scale is set by \( I_{s}=200 \mathrm{~W} / \mathrm{m}^{2} \), and the horizontal axis scale Figure 32-29 is set by \( r_{s}^{-2}=8.0 \mathrm{~m}^{-2} \). What is the power of the source?
