Detailed explanation-1: -Here kilohertz is also a unit of frequency of waves and is defined as 1000 cycles per second. Radio waves are measured in kilohertz (KHz).
Detailed explanation-2: -Frequency is measured in the unit hertz (Hz), referring to a number of cycles per second. One thousand hertz is referred to as a kilohertz (kHz), 1 million hertz as a megahertz (MHz), and 1 billion hertz as a gigahertz (GHz). The range of the radio spectrum is considered to be 3 kilohertz up to 3, 000 gigahertz.
Detailed explanation-3: -Frequency is number of complete waves passing per unit time. It is measured in Hertz (Hz), the number per second.
Detailed explanation-4: -plural kilohertz (written abbreviation kHz) a unit of measurement of radio waves that is equal to 1, 000 hertz. Miscellaneous units of measurement.
