Radio frequency (RF) is a measurement representing the oscillation rate of electromagnetic radiation spectrum, or electromagnetic radio waves, from frequencies ranging from 300 GHz to as low as 9 kHz. With the use of antennas and transmitters, an RF field can be used for various types of wireless broadcasting and communications.
RF (radio frequency) is an electromagnetic wave form that can be distorted by metal and magnetic fields but can travel in a vacuum. ultrasound is a physical wave form that requires a medium to travel in (solid or liquid) and will not travel in a vacuum.
