Scientists group electromagnetic waves into categories according to their wavelength. Technically a radio wave has a longer wavelength then a microwave but that's the only fundamental difference. They are both electromagnetic waves.
Microwave ovens do not need to preheat, it is not good to run them without food inside. This can damage the oven.
About enough to run 3 conventional kitchen ovens or 30 microwave cookers or 300 hundred watt lightbulbs.
For a great low priced service on your microwave oven, try A & P Appliance. They repair microwaves, as we as sell parts for them, so you won't have to run around looking for parts.

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).
because the signals run through wires, not radio waves like cell phones do.
Most people would think that microwaves use heat to warm up the food, but that isn't true. As you know almost every food has traces of water. What a microwave does is it send waves of electricity which "excites" the water inside the food. When water is "Excited" it produces heat which warms up the food. So basically the food warms it's self up. For example have you seen when lightining strikes a tree?. The tree sets on fire because the lightining " Excites " the water in the tree. So then the tree produces heat and sets it self on fire because it produced too much Hope this helped
The power consumption rate is 1200 Watts on a 120 Volt Input. There are 10 adjustable power levels and the microwave requires 1,100 watts to run. This Sharp Microwave is rated at 1000 watts, though actual power consumption will vary. The Sharp 1.5 Cu. Ft. Over-the-Counter Microwave Oven has a wattage of 1100 W and is not an energy star appliance. The microwave runs on 120 volts, and the cooking wattage is 1200.

Yes, radio waves can be harmful if a person is careless around them to a foolish degree. Examples: -- Jury-rigging the interlock switch in your microwave oven, so that you can run it with the door open. -- Sitting down in a lawn chair to eat your lunch, read the newspaper, and catch a nap, 6 feet in front of a Doppler Radar antenna.
The signal that the cable uses is either the wireless connection or the electromagnetic waves.
