When it is said that a radio station has a frequency of 102 megahertz, it means that the station broadcasts its signal at a frequency of 102 million cycles per second. The unit "megahertz" (MHz) represents one million hertz, where hertz is the unit of frequency. In other words, the radio station transmits its signal at a rate of 102 million waves per second, which determines the specific location on the radio dial that listeners can tune in to receive the station's broadcasts.
