Same way a radio transmitter produces radio waves. The device is called a magnetron, which is sometimes used as a pars pro toto for the whole microwave oven.
Sound waves, ocean waves, micro waves, light waves and etc.By the way microwave is not the microwave you warm stuff up in.
two things 1 what you put in it and 2 actual micro waves
The prefix micro in microwave is not maen to suggest a wavelenght in micrometer range.it indicates that microwave are small compared to waves used in typical radio broadcasting in that they have shorter wavelenght.
"Microwave" IS radio waves. They're called microwaveswhen their frequency is 3 GHz or higher.
I think it is to do with the wavelenght of the sound waves. I think there are tiny holes in the microwave and the sound waves are small enough to escape out of the microwave - meanig we can hear our food cook!
Microwaves are not harmful, the only time when they are harmful is if the microwave is broken, as it can then emit harmful rays.
Microwave cookware can be made from a variety of materials. The biggest material used is polypropylene to make microwave cookware. Glass and organic minerals can also be used to make microwave cookware.
the microwave is a wavelength of light beyond the human visible spectrum. the full spectrum of light as known by current science from smallest wavelength to longest is; y rays, x rays, UV (ultraviolet), the visible spectrum, infra red, micro waves, radio waves (including FM and AM frequencies), and long radio waves so a microwave is a wavelength of light longer then infra red, and shorter then radio waves.
It depends, if you need it done fast use the microwave, if you need it slow cooked use the mini oven.
Micro waves heat by vibrating the conductive molecules in items. Pure water (which has no impurities) does Not boil in a microwave oven. It does get extremely hot! Be care and use the recommended time for that your microwave states for water.

There are several types of waves, including mechanical waves (such as water waves and seismic waves), electromagnetic waves (such as light and radio waves), and matter waves (such as those associated with particles at the quantum level). Each type of wave carries energy in different forms and exhibits different behaviors.
