Introduction – National Microwave Oven Day is observed annually on December 6 to commemorate the invention of the most influential kitchen appliances. Microwave ovens are used in making several varieties of delicious dishes such as pudding, cakes, popcorn, reheated food, and many more. It uses less energy as compared with conventional ovens about 80 percent.
History – Percy Spencer, an American engineer, invented a microwave oven to heat and make food securely with microwaves. Percy was working at Raytheon Technologies Corporation in the United States in the early 1940s for developing combat radar equipment by using magnetrons for the Radiation Laboratory of the Massachusetts Institute of Technology (MIT). He invented the microwave oven by chance.
In past, Spencer noticed a chocolate bar in his pocket melting during working with an active radar in the year 1945 which led to the invention of microwave ovens. The high-powered microwave beam created a heating effect in the microwave oven which is perfect for cooking delicious food. Percy deliberately attempted to cook popcorn with the help of a microwave. Later, he cooked an egg in the microwave oven.
Originally, Raytheon made the first commercially available microwave oven was called as ‘’Radarange’’. on October 8th, 1945, and the company filed a patent application for the microwave cooking process which was made by Spencer. Presently, there is about 90 percent of homes in the United States have a microwave in them.
Significance – A microwave oven is a very popular kitchen appliance, which cooks and heats or reheats food securely by using microwave radiation in the electromagnetic spectrum in a very quick time and maintains the nutrients in food. Microwave oven is simple to use so everybody uses microwave oven to make delicious dishes including cakes, pudding, reheat food, and many more across the world.
