A microwave oven (also commonly referred to as a microwave) is an electric oven that heats and cooks food by exposing it to electromagnetic radiation in the microwave frequency range.This induces polar molecules in the food to rotate and produce thermal energy in a process known as dielectric heating.Microwave ovens heat foods quickly and efficiently because excitation is fairly uniform in the ...

The microwave oven did not come about as a result of someone trying to find a better, faster way to cook. During World War II, two scientists invented the magnetron, a tube that produces microwaves.
Raytheon filed a patent on October 8, 1945 for a microwave cooking oven, eventually named the Radarange. In 1947, the first commercially produced microwave oven was about 6 feet tall, weighed about 750 lbs, and cost about 5,000 US$. In 1967 the first relatively affordable ($495) and reasonably sized (counter-top) microwave oven was available ...
John has complained in recent years at IEEE talks that some web sites propose that the microwave oven was invented in Russia, or Germany, but then again, you can find almost any incorrect "fact" you you are looking for on the internet. Below is a video of John talking about the invention of the microwave oven:
The Amazing True Story of How the Microwave Was Invented by Accident. ... Today the sights, sounds, and smells of the microwave oven are immediately familiar to most Americans.
