Read moreWhat are high frequency waves called?
High frequency (HF) is the ITU-designated range of radio frequency electromagnetic waves (radio waves) between 3 and 30 MHz. It is also known as the decameter band or decameter wave as the wavelengths range from one to ten decameters (ten to one hundred metres).
Read moreWhat uses super high frequency?
Super High Frequency (SHF): 3-30 GHz Given their ability to carry enormous amounts of data, super high frequency waves are used for relaying broadcast programs (STL/TSL/TTL), radar (weather, etc.), satellite communications and satellite broadcasting, and other applications .

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 moreWhat is considered low frequency noise?
Abstract. Low frequency noise, the frequency range from about 10 Hz to 200 Hz , has been recognised as a special environmental noise problem, particularly to sensitive people in their homes.
