- Acoustic energy [r]: Energy propagated as pressure waves, through elastic media such as air or water. Hearing is the detection of acoustic energy within the frequency range of the animal detecting the energy [e]
- Electromagnetic spectrum [r]: The range of electromagnetic waves covering all frequencies and wavelengths. [e]
- Electromagnetic wave [r]: A change, periodic in space and time, of an electric field E(r,t) and a magnetic field B(r,t); a stream of electromagnetic waves, referred to as electromagnetic radiation, can be seen as a stream of massless elementary particles, named photons. [e]
- Periodic processes [r]: Add brief definition or description
- Vibrational spectrum [r]: The set of frequencies exhibited by regular, periodic motions of the parts of a mechanical system relative to one another that persist once excited without requiring an external driving agency. [e]
- Wavelength [r]: For a repeating phenomenon such as a radio signal with a given frequency, the wavelength is the length, in meters, of a single repetition [e]
- Microwave [r]: Add brief definition or description
- Radar [r]: (acronym for "radio detection and ranging") A technique used for detecting and tracking targets, navigation, imagery, and special applications. [e]
- Radio [r]: Transmission and reception of information, which can be voice, data or imagery over electromagnetic radiation in free space (i.e., wireless). The information is modulated onto a carrier wave [e]
- ITU frequency bands [r]: A terminological scheme by the International Telecommunications Union to broadly classify electromagnetic frequencies used for radio and radar. [e]
- IEEE frequency bands [r]: A terminological scheme by the Institute for Electrical and Electronic Engineers to broadly classify electromagnetic frequencies used for radio and radar. [e]
- EU-NATO-US frequency bands [r]: A terminological scheme by the European Union, the NATO and the U.S. military to broadly classify electromagnetic frequencies used for radio and radar. [e]
