High frequency radio waves used for telecommunications transmission. Line-of-sight, point-to-point transmission of signals at high frequency, usually above 890 MHz. Many cable television systems receive some television signals from a distant antenna location with the antenna and the system connected by microwave relay. Microwave frequencies require direct line-of-sight to operate. Trees and buildings distort or block the signal.
Microwaves are a form of energy similar to television and radio waves. Instead of transforming electrical waves into pictures and sound, they are transformed into heat to cook food.
That part of the electromagnetic spectrum at which the wavelength falls between about 30 centimeters and 1 millimeter. Microwave frequencies range from 1 GHz to 300 GHz. Microwaves are very short electromagnetic radio waves but have a long wavelength than infrared energy
A type of radiation used for heat sealers, ovens, radar, and communications. A physical hazard.
Electromagnetic waves of sufficiently short wavelength that practical use can be made of waveguide and associated cavity techniques in their transmission and reception. Note: the term is taken to signify waves having a frequency range of 300 MHz-300 GHz.
The electromagnetic waves of very high frequency used for heating and communication purpose.
Radiation with wavelengths in the approximate range of 0.1 mm to 1 meter.
Electromagnetic radiation with a frequency at the high end of radio-frequency radiation. A form of nonionizing radiation. Radar is a form of microwave radiation. Microwave ovens operate at 2,400,000,000 Hz.
High frequency radio waves lying roughly between infrared waves and radio waves (above 1 GHz = 1 billion cycles per second). Microwaves are generated by electron tubes, such as the klystron and the magnetron, or solid state devices with built-in resonators to control the frequency or by oscillators. Microwaves have many applications for radio, television, radar, test and measurement communications, distance and location measuring, and more.
Microwaves are radio frequency signals with extremely high frequencies (EHF) in the range of one gigahertz and above.
Electomagnetic waves with a frequency between radio and infrared.
Electromagnetic waves at frequencies 915, 2450, 5800, and 24225 MHz.
These are point-to-point transmissions of electromagnetic signals at high frequencies (between 890 MHz and 20 GHz). They can be used for all types of information transmission, but with the advent of fiber-optic technology the use of microwave relays has lessened.
Very high frequency radio waves that can carry large amounts of information very efficiently. Used both for satellites and on the ground.
Electromagnetic radiation with wavelength intermediate between radio wave and infrared radiation.
Microwave therapy is a kind of deep heat therapy. The electromagnetic waves pass between electrodes placed on the patient's skin. This creates heat that increases blood flow and relieves muscle and joint pain
Electromagnetic radiation with a frequency between that of visible light and radio waves. Waves
radiation with a wavelength between approximately 1 mm and 30 cm.
Radio waves that provide a high-speed signal transmission; involves sending signals from one microwave station to another. 9.37
A subset of radio waves that have frequencies ranging from around 300 million waves per second (300 MHz) to three billion waves per second (3 GHz).
