Microwave ovens heat food by generating microwaves; to think of it slightly differently, it is a special kind of radio signal at 2.45 GHz - very similar to Wi-Fi frequencies, but considerably more powerful. Microwave ovens typically produce about 700 Watts of microwave energy, while Wi-Fi uses 0.1 Watt. The microwave energy causes the dipole and induced-dipole molecules of the food to rotate. This process may be difficult to understand, but here is an analogy that gets at the general idea. The process is sort of a combination of two concepts:
1) Imagine moving a magnet close to, and then away from, a compass. The needle swings around to align with the magnet when they are together, then swings away when they are separate.
2) The microwaves move through space as a wave. The wave action is similar to waves on water, making a floating object bob up and down as they pass.
In this case, the microwaves make the molecules rotate, instead of bob.
The microwaves are produced by a generator called a magnetron that is powered by electricity. The reason the microwave energy cannot 'escape' the microwave (even through the little holes in the window screen!) is because the waves cannot 'fit' through the holes in the metal screen, and the microwaves are blocked by the metal in general. The concept of them 'fitting' through the holes is a bit more complicated than just that, but that is essentially how it works.

Does a microwave have chemical energy?
If you are referring to the oven, the answer could be yes, as the turn table moves. However if you are referring to the electromagnetic wave known as a microwave then this is a form of electromagnetic energy...
Can you use ever-silver utensils in microwave oven?
No metal object should be used in a microwave.
Why do you put plastic in microwave ovens?
The Reason for these is because Some Plastic Can Not Stand the heat that The MicroWave Oven melt produce therefore when you put a unstsble Plastic in the Microwave oven it Will meltAnother Response:Certain types of plastic may be recommended for use in microwave ovens because they allow the microwaves to pass through them. In this way the food inside the plastic container is cooked while the container stays cool. Not all plastics are microwave safe; some will melt. Metal cannot be used in microwaves. Some types of ceramic dishes, which may have metal elements in their glaze, are not safe in microwave ovens. Consequently some companies such as Tupperware, Rubbermaid and Pampered Chef produced lines of plastic cookware specifically for microwave ovens.More recently, studies suggest that molecular particles from some types of plastic migrate into food when heated in microwave ovens. While manufacturers maintain that their products are safe, some medical experts advise using only glass or safe ceramic cookware in microwave ovens.
What form of energy is the spinning plate inside of the microwave?
A plate, whether spinning or not, is matter, not energy. However, it possesses kinetic energy if it's moving.
What energy source does a microwave use?
They are powered by electricity of course, but the generate microwaves (an electromagnetic wave, like light - but of a higher frequency). We are surrounded by microwaves from the sun, satalites, and radiation from electrical dewvices, but microwaves concentrate the energy - heat happens where "beams" cross and excite the molecules of what they are passing through (i.e. heat).
What are three types of energy associated with the microwave?
Three types of energy associated with microwaves are electrical energy used to power the microwave, electromagnetic energy emitted by the microwave to heat food, and thermal energy generated in the food as it absorbs the microwaves and heats up.
Is the Panasonic Energy Star approved?
No, this microwave is not energy star approved. In fact, Energy Star does not currently approve/label ANY microwave ovens. However, most microwave ovens of the same size/wattage use comparable amounts of energy, and microwave ovens use substantially less energy than conventional ovens.
Does a microwave use machanical energy?
because It moves
Is there a light inside of the microwave when it is not in use?
No, when it is not in use, the microwave would not have a light on. Why would you want the light on when you are not using it and waste energy?
Does a microwave use heat energy?
Yes, microwave uses heat energy. It helps in cooking.
Why does a microwave use less energy than a conventional oven?
Microwave takes less time to cook
What is an example of electromagnetic energy in the kitchen?
All types of radio waves are electromagnetic energy, and that includes microwaves from the microwave oven.
What kind of energy does a microwave oven use?
A microwave oven uses electricity to generate electromagnetic radiation in the microwave frequency range. This radiation is absorbed by water, fats, and sugars in food, causing them to vibrate and generate heat, which cooks the food.
What gives out the microwave?
Microwaves use radiant energy, so they give off radiant energy.
What energy powers a microwave?
A microwave oven uses the 120 V AC coming out of your kitchen receptacle (in the United States) and by means of a transformer and rectifier converted to 7000 V DC which is then used to energize the magnetron that creates the microwave energy.
Is it safe to use a microwave spoon for heating food?
No, it is not safe to use a metal spoon in a microwave to heat food as it can cause sparks, fires, and damage to the microwave. It is recommended to use microwave-safe utensils made of materials like glass, ceramic, or certain types of plastic.
What energy is wasted by a microwave?
Inefficiencies in the microwave's components can lead to wasted energy in the form of heat loss, especially in older models. Additionally, leaving the microwave running when not in use or using it to heat empty containers can also contribute to wasted energy.
