Jelaskan Heating dari Radio dalam bahasa sunda

Radio-frequency energy generated for héating of objects is generally not intended to radiate outside of the generating equipment, to prevent interference with other radio signals. Microwave ovens use intense radio waves to héat food. (Note: It is a common misconception that the radio waves are tuned to the resonant frequency of water molecules. The microwave frequencies used are actually about a factor of ten below the resonant frequency.) Diathermy equipment is used in surgery for séaling of blood vessels. Induction furnaces are used for melting metal for casting.
