Intensity versus inverse-square distance from the source.
An isotropic transmitter emits electromagnetic radio waves uniformly in all directions through space. A detector measures the wave intensity \(I\) at various distances \(r\) from the source. A graph of the measured intensity \(I\) as a function of \(\dfrac{1}{r^2}\) is shown. Based on the graph, what is the total power emitted by the transmitter?
