Web14 de jan. de 2024 · Radio waves have many uses—the category is divided into many subcategories, including microwaves and electromagnetic waves used for AM and FM radio, cellular telephones and TV. The lowest commonly encountered radio frequencies are produced by high-voltage AC power transmission lines at frequencies of 50 or 60 Hz. WebWatch on. There has been some concern over the potential for microwaves to damage the brain, but the evidence suggests that it is unlikely. Microwaves are a form of electromagnetic radiation, similar to radio waves, but at higher frequencies. They are used in microwave ovens to heat food and in telecommunications to transmit information.
