Satellites use breams of EM waves to communicate with devices on Earth. Suppose a particular satellite has a power of 18 kW and sends a focused cone of EM waves toward Earth 4.9x10^2 km away. When the focused beam reaches the Earth, its circular diameter is about 1.3 km. What is the peak electric field strength in this focused beam?
