Can anybody explain diffrent types of Microwave ovens ?
Microwave ovens cook food by emitting microwaves, which are high-frequency electromagnetic waves. Directed into the oven cavity, microwaves cause the molecules in food to vibrate, which in turn creates friction resulting in heat. The heat produced by the molecular friction cooks the food from the inside out. Since microwaves are absorbed only by molecules inside the food, whose vibrations produce heat, and not by the surrounding air, the cooking and baking time is greatly reduced compared to other types of ovens. Microwave ovens are easier to use than the conventional kitchen range for simple cooking tasks, such as heating leftovers, making popcorn, defrosting frozen foods and cooking pre-packaged meals. They also perform more quickly than the conventional kitchen range. However, foods are steamed, resulting in surfaces that are smooth, moist, and not crisp unless special accessories or packaging is used. Uneven heating is also common unless the food is stirred or rearranged occasional
