Question

Microwaves are produced when

magnetic and electric fields are applied parallel to each other
magnetic and electric fields are applied perpendicular to each other
transverse and longitudinal waves are applied parallel to each other
transverse and longitudinal waves are applied perpendicular to each other

Answer 1

"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."
