The microwave oven is a wildly popular kitchen appliance owned by over 90% of Americans. It’s an electric oven that heats and cooks food by exposing it to electromagnetic radiation in the microwave frequency range.
There are few foods and beverages the microwave can’t heat. With the simple touch of a button, you can boil water, reheat leftovers, pop popcorn or defrost frozen meats in mere minutes thanks to this uber convenient appliance.
Microwaves are able to heat food so quickly because they channel heat energy directly to the molecules inside food.
American inventor Percy Spencer is credited with inventing the microwave oven, using radar technology developed after World War 2.
