A microwave oven or simply microwave is an electric oven that heats and cooks food by exposing it to electromagnetic radiation in the microwave frequency range. [1] This induces polar molecules in the food to vibrate [ 2 ] and produce thermal energy in a process known as dielectric heating .
Raytheon patented the dielectric heating device, naming it the Radarange, and in 1947 the first commercially available microwave oven hit the market. What started as an 800-pound device priced ...
The result was the egg exploding in the face of one of his co-workers, who was looking in the kettle to observe. Spencer then created the first true microwave oven by attaching a high-density electromagnetic field generator to an enclosed metal box. The magnetron emitted microwaves into the metal box blocking any escape and allowing for ...
Yes, the microwave oven was invented accidentally, when a test for a magnetron melted an engineer’s snack in 1946.. Raytheon engineer Perry Spencer “knack for finding simple solutions to ...
He investigated cooking with microwaves and invented the microwave oven, consisting of a magnetron feeding microwaves into a closed metal cavity containing food, which was patented by Raytheon on 8 October 1945. Due to their expense microwave ovens were initially used in institutional kitchens, but by 1986 roughly 25% of households in the U.S ...
