Question

How can radio-frequency produce heat?

Answer 1

Answer:

Radiofrequency (RF) radiation, which includes radio waves and microwaves, is at the low-energy end of the electromagnetic spectrum. It is a type of non-ionizing radiation. ... If RF radiation is absorbed in large enough amounts by materials containing water, such as food, fluids, and body tissues, it can produce heat.

Answer 2

Answer:

Radio frequency is short for RF, which is a kind of high frequency alternating current electromagnetic wave with frequency range from 3k hz-3k GHz

Because the frequency is high, so the molecular movement speed is fast, and the physical explanation of the heat of the object 100 is its internal molecular movement speed, the use of radio frequency energy to make the molecular high speed movement of course will achieve the purpose of heating
