Microwaves are made using a variety of minerals and materials, including silicon, aluminum, iron, copper, and nickel. These minerals are used in components such as the magnetron (generates microwaves), the waveguide (transmits microwaves), and the cooking chamber.


Do microwaves use microwaves?

Microwaves are radio waves with frequencies above 3 GHz. They are used to communicate great volumes of information over distances up to 100 miles, at data rates up to several hundred megabits per second per carrier. Certain high-power devices use UHF radio waves to boil water and heat meatloaf. They are marketed under the generic name "microwave ovens" and referred to as "microwaves" by the population at large, even though they use radio waves at 2.45 GHz and, technically, fall 550 MHz short of rights to the title.
