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 rotate and produce thermal energy (heat) in a process known as dielectric heating.
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 ...
A microwave oven passes microwave radiation at a frequency near 2.45 GHz (12 cm) through food, causing dielectric heating primarily by absorption of the energy in water. Microwave ovens became common kitchen appliances in Western countries in the late 1970s, following the development of less expensive cavity magnetrons. Water in the liquid ...
In 1947, just a year after Spencer’s snack food serendipity, the first commercial microwave oven hit the market. Called the “Radarange,” it weighed nearly 750 pounds and cost more than $2,000 .
It not only changed the course of the war by allowing us to develop airborne radar systems, it remains the key piece of technology that lies at the heart of your microwave oven today. The cavity magnetron's invention changed the world." [3] Randall also led the King's College, London team which worked on the structure of DNA.
The term is an acronym for microwave amplification by stimulated emission of radiation. Nikolay Basov , Alexander Prokhorov and Joseph Weber introduced the concept of the maser in 1952, and Charles H. Townes , James P. Gordon , and Herbert J. Zeiger built the first maser at Columbia University in 1953.
Microwave ovens operate by emitting electromagnetic waves, particularly microwaves, which interact with water molecules in the food. These microwaves cause the water molecules to oscillate rapidly ...
The cake is a bit denser than when baked in an oven, but has a good texture, and flavour is the same. The size is great, if you're only baking for one or two people. Plus it's very easy to throw ...
