Electromagnetic radiation.
No, there is no scientific documented evidence that microwaves give you cancer.
LEAD ABSORBS MICROWAVESSorry, but lead really doesn't effectively absorb microwaves - it is primarily reflective with only a trivial amount of "absorption". The term "absorption isn't quite quite correct - it really should be "attenuation" i.e. the microwaves are attenuated - lose their energy which can then be converted to heat - as they penetrate into a material. In that sense, water is a good microwave absorber, as are moist foods generally.In a broad sense, all materials are either primarily reflectors of the microwaves - such as aluminum; transparent to them - such as glass, paper or many plastics at lower temperatures; absorbers or attenuators - such as water, tea, moist foods, polar solvents such as nitrobenzene. However, all materials will exhibit all three properties but to a different extent - aluminum primarily reflects microwaves, but they do penetrate to a very tiny amount referred to as the skin-depth and so can caused a trivial amount of heat.
That means that both the frequency and the wavelength of microwaves are also between those of infrared and radio waves.
Yes they are.
a magnetron produces microwaves
A magnetron tube inside of the microwave produces the waves and a fan circulates them.
A klystron, magnetron or travelling-wave tube will generate microwaves. So will a vircator and an inductive output tube. These are just some of the vacuum tubes used to generate microwaves. In a microwave oven, the magnetron, which is a type of cavity resonator, is the device of choice.
The key components of a microwave cavity are the walls, the magnetron, and the waveguide. The walls of the cavity reflect and contain the microwaves, the magnetron generates the microwaves, and the waveguide directs the microwaves into the cavity. These components work together to efficiently generate and distribute microwaves for cooking or heating food.
a microwave is actually a particle of light below the visible spectrum that we can see. a magnetron is the device in a microwave oven that produces the microwaves by using an electromagnet that charged produces a light wave at the proper frequency to make it a microwave.
Microwave frequency radio waves are usually produced by a MAGNETRON.
Microwaves in a microwave oven are produced by a component called a magnetron, which converts electrical energy into electromagnetic waves that heat up food.
Eventually - over time the magnetron loses its ability to produce sufficient quantities of electrons (the source of the microwaves cooking ability) to cook food properly.
It shouldn't because the magnetron, the device that makes the microwaves have very strong magnets in them already.
A magnetron, a type of magnet used in microwaves, generates the microwaves that heat food in a microwave oven. The magnetron produces electromagnetic waves that excite water molecules in the food, causing them to vibrate and generate heat, which gently cooks the food.
Microwaves are generated at the atomic level, based on the frequency of the EM radiation that it emits. This is conducted through radiation that is absorbed, reflected, attenuated, or refracted.
Microwaves are electromagnetic waves with a frequency of about 2.45 GHz and a wavelength of about 12.2 cm; in the electromagnetic spectrum, they fall before infrared light but after radio waves (Heckert 2007). In a microwave oven, microwaves are produced by a device called a magnetron.-Google
