A microwave oven is a machine that cooks food using microwaves, a type of radio wave. The microwave oven is commonly called a microwave. The idea was invented when a scientist who was experimenting with radio waves saw his chocolate bar, which he was holding at that time, melt. He then knew that radio waves could cook food and he eventually invented the microwave oven. Food is placed inside the oven, and buttons on the screen are pressed to see how long the food should be cooked. A microwave oven is one of the fastest ways of cooking. When the oven is started it sends microwaves. These waves go and touch the water molecules. Then the water molecules start vibrating against each other at a very high speed this generates heat. Fats and sugars are heated less than water, and other foods much less. The turntable moves so that the food is heated evenly. Microwaves can go through materials such as fine China bone, glass or special plastic materials. Metal such as aluminum foil cannot pass the radiation because when the waves come to it they reflect from it and go away. The microwave oven can be used to cook food or only heat it up.
• Look for must-have features like automatic defrost and preprogrammed settings that warm up snacks. Also look out for features like sensors that calculate cooking time-based on the amount of steam the food emits.
• Make sure to check out the size of the turntable. See if your favorite dish fits on the turntable. If the dish is too wide to rotate, look for a feature that lets you shut off the turntable so it's stationary during cooking.
Find out if the machine is user-friendly. Look for large buttons and icons. Open and close the door a few times to see if you like the way it feels.• Look for microwave ovens with easy-to-read preprogrammed settings. They make preparing snacks like popcorn and soup very easy.
