![]() That radio station broadcasts in Spanish from Miami, Florida. For example, the Radio Marti shortwave broadcasting station's antenna will vibrate at a frequency of 11.930 MHz (11,930,000 times per second). Two shortwave antennas that are cut to vibrate at the same frequency will behave like the two tuning forks in my example. Note that the " receiver" fork will only vibrate faintly because much of the sound wave energy will have been lost over the distance separating the two forks.
