Radio station KNAU’s effective radiative power (a measure of how much radio energy it delivers to its listening area) is 100 kW. It broadcasts at 88.7 MHz. Suppose KNAU had a spigot that poured out water molecules as quickly as its antenna pours out photons. How many liters/second of water would it produce?
