True - they work by using microwave radiation.
Radio waves - radiation don't worry everything gives off some kind of radiation even you
The type of radiation produced by cellular phones is electromagnetic RF microwave radiation, not nuclear radiation. They produce it in their transmitter circuits needed to send signals to connect with the cell tower, dial numbers, send your voice, send your text messages, etc. If a cellular phone did not produce this RF microwave radiation, it could not do any of these things you use it for and would thus be useless. If the frequency of… Read More
microwave radiation is radiation that comes from microwaves
To produce RF power used in accelerating the charge particles.In agriculture ,in telecommunication it is used.
Microwave is lower frequency.
stars but mostly they produce visible light then infrared ultraviolet and then in very small proportions microwave, radio, x ray electromagnetic radiation
A microwave oven generates microwave radiation, which is a form of non-ionizing electromagnetic radiation. Links can be found below for more information.
All ultraviolet radiation has shorter wavelengths than any microwave.
All ultraviolet radiation has shorter wavelengths than any microwave.
A microwave heats food by radiation No, a microware works with microwaves, not radiation.
Yes, microwave ovens use electromagnetic radiation.
microwave is an electromagnetic wave in order of micrometer (one thousandth of meter). Because every electromagnetic wave is a radiation, microwave is radiation. Therefore, microwave oven which utilize microwave is transferring the heat via radiation.
microwave ovens and microwave communications.
microwave radiation does not cause ionization because it has a low photon energy so therefore it has a small heating effect. the main effect of microwave radiation is warming.
In the 1960s, microwave radiation was detected coming from space and no particular source, and this radiation was dubbed the Cosmic Microwave Background Radiation (CMBR).
"microwave" is technically a slang term for "microwave oven," so there isn't any difference. If you really want to get technical, a microwave is a little bit of radiation, and a microwave oven sends out the radiation to cook food.
There is a switch connected to the door that prevents leakage of microwave radiation. The door reflects the radiation back into the microwave, and the switch prevents the operation of the microwave if the door is not securely closed.
microwave radiation is called "electromagnetic" radiation
The Cosmic Microwave Background Radiation was first discovered, completely by accident, in 1964.
this is radiation in the microwave part of the electromagnetic spectrum which comes from all directions in outer space
Nobody, microwave radiation is a natural phenomena and part of electromagnetic radiation (higher in frequency than UHF and lower in frequency than IR).
Yes, microwaves cook with radiation. Electromagnetic radiation in the microwave band. It's non-ionizing, but it works well to heat things up.
Into microwave electromagnetic radiation.
Microwave radiation won't heat a room. For microwave radiation to heat something, the "something" must contain water . It is the water molecules which get heated. Irradiate a room with microwaves and you are likely to kill the cat.
Microwave ovens employ microwave radiation, which is lower in frequency than infrared radiation, to generate the heat in the food they cook. They don't use infrared radiation per se.
Microwave oven is used to create microwave radiation of suitable freq....
Yes, although probably not the kind you're thinking about. Microwaves use electromagnetic radiation to heat food. If the microwave is properly constructed and not damaged, none of that radiation escapes.
The evidence of cosmic microwave background radiation supports the Big Bang theory.
Both visible light and microwave radiation are different variations of the same electromagnetic energy. Visible light has infinitesimally small wavelengths, and therefore it can pass through the screen holes. Microwave radiation has much larger wavelengths, and these wavelengths are too big to "fit" through the screen holes, and therefore the screen appears solid to the microwave radiation. The microwave radiation is therefore completely reflected by the screen.
Leakage of microwave radiation past the door seal in a microwave oven.
It transforms electrical input energy into microwave EM radiation, this radiation then agitates water molecules in food to raise the temperature.
Both microwave radiation and nuclear electromagnetic radiation are members of the same species, but they're as different as babies are from elephants, to wit, microwaves are much, much less powerful than nuclear electromagnetic radiation. Microwave radiation, for instance, makes atoms shift their position (and magnetic fields) very, very quickly. Now the definition of heat is "movement," so the faster anything moves, the "hotter" we say it is. Ergo, something placed in a microwave-radiation-field becomes noticeably… Read More
Yes and No...and this is because microwaves produce radiation in little amount that are of not much danger to humans but if you keep yourself close to a microwave for a long period of time the radiation would be able to reach you and damaged some of your internal skin parts....
Where is the microwave radiation located on the electromagnetic spectrum in relation to other kinds of radiation?
Microwave is higher frequency than radio and lower frequency than IR.
Electricity drives it, and microwave radiation is produced. This is a form of electromagnetic radiation with a wavelength intermediate between infra red (heat) and radio waves.
The purpose of the microwave is to heat the food or defrost it with radiation waves! XD :)
No, a microwave is purely electromagnetic radiation of a certain frequency
At microwave frequency, water molocules resonate, creating heat.
Ozone does not absorb microwave. It only absorbs UV.
A microwave is a form of electromagnetic radiation and has no intrinsic weight.
Standing next to a campfire you will be warmed by its radiant heat (IR radiation). However a microwave cooker generates heat by boiling water inside the food, then the steam heats the food by a combination of conduction and convection (not radiation). There is some trivial heating of the microwave cooker's walls by IR radiation from the hot food, but this is so trivial you will not be able to measure it and the steam… Read More
Yes. The radiation is microwave radiation (frequency about 1-2 GHz).
Pfft. No. It uses Radio Signals. Not Radiation.. Radiation is from the Sun and Microwave Signals. :)
The advantages and disadvantages of microwave radiation is that it is extremely harmful to humans and living things in general however it is very useful.
Cosmic microwave background radiation.
Conventional ovens cook by radiation, as do microwave ovens.
Radiophobia is the fear of ionizing radiation, and is most commonly portrayed as a fear of X-Ray devices, but it can also apply to other devices that produce radiation (such as a microwave oven) . Cyberphobia is the fear of technology such as computers, and computer controlled devices (such as a microwave oven). Beyond that, there isn't a specific, named phobia, that describes only the fear microwaves and substances that have been microwaved.
Microwave telescopes can allow us to see the sky in microwave frequencies. There are microwave sources that are invisible to optical telescopes, and there may be gas or dust clouds that block visible light but allow some microwaves to penetrate. A breathtaking example of the use of a microwave telescope is seen in the microwave mapping of the sky. As we understand it, the universe began with the Big Bang, which was that massive outrush… Read More
