How do microwaves heat things?
Microwaves are electromagnetic radiation and part of the Electromagnetic Spectrum, along with radio waves, infared, visable light, ultraviolet, x-rays, and gamma rays. Microwaves do not have enough energy to remove electrons from the orbits of atoms, putting it in the class of non-ionizing radiation. Electromagnetic radiation is energy in transfer by electromagnetic waves. These waves move at the speed of light. Microwaves have a range of frequencies of 0.03 to 300 GHz, placing it between Radio-frequency and Infared radiation in the Electromagnetic Spectrum. Hertz (Hz) is a measure of frequency, the number of times per second that the waves oscillate, in the electric and the magnetic directions. (Note: “GHz” means a billion hertz, or a billion of times per second ). Microwave ovens often use 0.9 or 2.5 GHz for their heating frequencies.
