Radio frequency (RF) is a measurement representing the oscillation rate of electromagnetic radiation spectrum, or electromagnetic radio waves, from frequencies ranging from 300 gigahertz (GHz) to as low as 9 kilohertz (kHz) .
Read moreWhat is high frequency and low frequency?
The lower the frequency, the fewer the oscillations. High frequencies produce more oscillations . The units of frequency are called hertz (Hz). Humans with normal hearing can hear sounds between 20 Hz and 20,000 Hz.
Read moreWhat is medium frequency and high frequency?
Frequencies immediately below HF are denoted medium frequency (MF), while the next band of higher frequencies is known as the very high frequency (VHF) band . The HF band is a major part of the shortwave band of frequencies, so communication at these frequencies is often called shortwave radio.
Read moreWhat is meant by frequency range?
(1) A group of frequencies in the electromagnetic spectrum that are assigned by regulatory agencies for a particular purpose . Also called a “frequency band.” See frequency bands, spectrum, satellite frequency bands and optical bands. (2) A group of frequencies that occur naturally such as the audio spectrum.
Read moreWhat are the frequency range?
The generally established audio frequency range is 20 Hz to 20,000 Hz , though most people can hear less than this entire range, and as they get older, the range tends to contract on both ends. The relationship between music and audio frequency is that each time you move up an octave, you double the frequency.

A high-pitched whistle, squeal, and a child’s voice are high-frequency sounds.
Read moreWhat is the low frequency range?
Low frequency (LF) is the ITU designation for radio frequencies (RF) in the range of 30–300 kHz . Since its wavelengths range from 10–1 km, respectively, it is also known as the kilometre band or kilometre wave. LF radio waves exhibit low signal attenuation, making them suitable for long-distance communications.
