Kilohertz means "thousand hertz." This is a unit of frequency that is equal to one thousand cycles per second. Hertz is the SI unit of frequency and is used to measure the number of cycles of a periodic wave that occur in one second. Kilohertz is commonly used to express the frequency of sound waves, radio waves, and other types of electromagnetic radiation. For example, the frequency of a typical AM radio station is around 1 kHz to 0.5 MHz, while the frequency of a typical FM radio station is around 88 MHz to 108 MHz. In general, the higher the frequency of a wave, the shorter its wavelength and the more energy it carries.
