How many GHz is a microwave?

Following international conventions, microwave ovens at home or in restaurants operate at frequencies of about 2.45 GHz , i.e. λ = 12. 23 cm. Figure 1 depicts a typical microwave oven (many details can be found in [1–3]). Microwaves are generated in a magnetron which feeds via a waveguide into the cooking chamber.

What kind of wave does 5G use?

The new network Millimeter waves use frequencies from 30 to 300 gigahertz, which are 10 to 100 times higher than the radio waves used today for 4G and WiFi networks. They’re called millimeter because their wavelengths vary between 1 and 10 millimeters, where as radio waves are on the order of centimeters.
