Microwavesare a form of high frequencyradiowaves similar to those used by a radioincludingAM; FM and CB. They are, however,much shorterthan radiowaves;approximatelytive incheslong.Electricityis converledinto microwaveenergy by the magnetrontube. Fromthe magnetrontube, microwave energyis transmittedand absorbed. Reflection Microwavesare reflectedby metaljust as a ball is bounced otf a wall.A combinationof stationary(interiorwalls) and rotatingantenna,locatedunderneaththe bottom shelf assure that the microwavesare well distributedwithinthe oven cavity to produceeven heatingor cookingof foods. Absorption Duringheatlng,microwaveswillbe absorbedby tood.They oenetrateto a deoth of about % to 1'l-inches.
