Ultraviolet radiation: A form of electromagnetic radiation having wavelengths shorter than visible light but longer than X-rays.
Infrared radiation: Electromagnetic radiation with a wavelength between visible light and microwaves.
Microwaves: A type of electromagnetic radiation with wavelengths ranging from about a millimeter to a meter.
Radio frequency (RF) radiation: Electromagnetic radiation with frequencies in the range of about 3 kHz to 300 GHz.
Extremely low frequency (ELF) radiation: A type of electromagnetic radiation with frequencies below 300 Hz.
Thermal radiation: Radiation emitted by a body as a result of its temperature, which is typically in the infrared range.
Ionizing radiation: Radiation that has enough energy to ionize atoms or molecules, potentially causing DNA damage and leading to cancer or other health issues.
"The range between 1 and 100 GHz"
"The entire SHF band (3 to 30 GHz)"
"S, C, X, Ku, K, or Ka band" or "similar NATO or EU designations"
"it indicates that microwaves are 'small' (having shorter wavelengths)"
"Microwaves travel by line-of-sight; unlike lower frequency radio waves, they do not diffract around hills, follow the earth's surface as ground waves, or reflect from the ionosphere"
"limited by the visual horizon to about 40 miles (64 km)"
"they are absorbed by gases in the atmosphere, limiting practical communication distances to around a kilometer"
"modern technology, for example in point-to-point communication links, wireless networks, microwave radio relay networks, radar, satellite and spacecraft communication, medical diathermy and cancer treatment, remote sensing, radio astronomy, particle accelerators, spectroscopy, industrial heating, collision avoidance systems, garage door openers and keyless entry systems, and for cooking food in microwave ovens" Note: Questions 10 to 20 are not directly answered in the given paragraph.
