What else can I help you with?
What are Microwaves infrared waves and gamma rays are all examples of?
Electromagnetic radiation.
Can microwaves give you cancer?
No, there is no scientific documented evidence that microwaves give you cancer.
Why does the human body absorb microwaves?
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.
On the electromagnetic spectrum microwaves are located between infrared waves and radio waves. Which is true for microwaves?
That means that both the frequency and the wavelength of microwaves are also between those of infrared and radio waves.
Are microwaves harmful?
Yes they are.
What is a source of a microwave?
a magnetron produces microwaves
What is the source of a microwave?
A magnetron tube inside of the microwave produces the waves and a fan circulates them.
Microwaves are generated in a vacuum tube called?
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.
What are the key components of a microwave cavity and how do they contribute to the efficiency of a microwave system?
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.
What are microwaves created by?
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.
What is the radiation source for microwaves waves?
Microwave frequency radio waves are usually produced by a MAGNETRON.
What produces microwaves in a microwave oven?
Microwaves in a microwave oven are produced by a component called a magnetron, which converts electrical energy into electromagnetic waves that heat up food.
Is it typical for a magnetron to stop functioning in a microwave?
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.
Does a magnet break a microwave?
It shouldn't because the magnetron, the device that makes the microwaves have very strong magnets in them already.
How is a magnet useful to a microwave?
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.
How are microwaves produced?
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.
How are micro waves produced?
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
