Read moreWhat uses very low frequency?
The VLF band is used for a few radio navigation services, government time radio stations (broadcasting time signals to set radio clocks) and for secure military communication . Since VLF waves can penetrate at least 40 meters (131 ft) into saltwater, they are used for military communication with submarines.
Read moreWhat has a low frequency sound?
Low-frequency noise is common as background noise in urban environments, and as an emission from many artificial sources: road vehicles, aircraft, industrial machinery, artillery and mining explosions, and air movement machinery including wind turbines, compressors, and ventilation or air-conditioning units .
Read moreWhich wave has highest frequency?
Gamma rays have the highest energies, the shortest wavelengths, and the highest frequencies. Radio waves, on the other hand, have the lowest energies, longest wavelengths, and lowest frequencies of any type of EM radiation.
Read moreWhat does it mean to be a high frequency wave?
The frequency of a wave is inversely proportional to its wavelength. That means that waves with a high frequency have a short wavelength , while waves with a low frequency have a longer wavelength.
Read moreWhat is the difference between low and high frequency waves?
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 a wave frequency?
The frequency of a wave refers to how often the particles of the medium vibrate when a wave passes through the medium . Frequency is a part of our common, everyday language.
