Speed of rf waves
WebThe RF part of the electromagnetic spectrum is generally defined as that part of the spectrum where electromagnetic waves have frequencies in the range of about 3 kilohertz (3 kHz) to 300 gigahertz (300 GHz). Probably the most important use for RF energy is in providing telecommunications services. WebRF radiation has lower energy than some other types of non-ionizing radiation, like infrared and visible light, but it has higher energy than extremely low-frequency (ELF) radiation. If RF radiation is absorbed by the body in large enough amounts, it can produce heat. This can lead to burns and body tissue damage.

WebCredit: NRAO/AUI. Radio waves have the longest wavelengths in the electromagnetic spectrum. They range from the length of a football to larger than our planet. Heinrich Hertz proved the existence of radio waves in the … WebPower density is defined as power flow per unit area. For example, power density is commonly expressed in terms of watts per square meter (W/m 2 ), milliwatts per square centimeter (mW/cm 2 ), or microwatts per square centimeter (µW/cm 2 ). One mW/cm 2 equals 10 W/m 2, and 100 µW/cm 2 equal one W/m 2.
