How micro waves are produced?

1 Answer

Answer :

Microwaves are electromagnetic waves with a frequency of about 2.45 GHz and a wavelength of about 12.2 cm; in the electromagnetic spectrum, they fall before infrared light but after radio waves (Heckert 2007). In a microwave oven, microwaves are produced by a device called a magnetron.-Google
