The ideal size (most efficient) for a broadcast antenna with one end on the ground is one-fourth the wavelength (λ/4) of the EM wave being sent out. If a new radio station has such an antenna that is 50.0m high, what frequency does it boradcast most efficiently? Is this in the AM or FM band. This analogous to what phenomenom encountered in our study of sound wave? (Note: AM band ranges from 540 to 1600 kHz, and FM band is between 88 to 108 MHz)

During the Cold War, American submarines operated as "lone wolves" at extreme ocean depths for many months at a time. Ordinary radio signals are greatly attenuated at such depths, making communication with the submarines difficult. One way suggested to communicate with the submarines was a program the Navy called Seafarer that used extremely low frequency waves. If the Seafarer transmitter broadcast at 82 Hz, what would the transmitter's quarter wavelength antenna have to be in order to receive the signal? km
