Microwaves are radio waves of very high frequency/ very short wavelength.
The exact boundary is not well defined, but frequencies over about one gigahertz (1 000 000 000 Hz) are generally considered "microwave". This boundary, as a wavelength, is anything shorter than about 30 cm.
The top end is also loosely defined, as extremely short "radio" waves eventually become infra-red radiation. "Microwaves" extend around 100 gigahertz in frequency, equal to one millimetre (1/10th of a centimetre) in wavelength.
The region between microwaves and infra-red is commonly known as "millimetre/millimetric" waves.

What is the average frequency of a microwave?
"Microwave" radiation is any radio wave at frequencies between 3 GHz and 300 GHz. Microwave cooking ovens are licensed to operate at a certain definite frequency, just like any other radio transmitter is. For microwave ovens in the US, the frequency is 2.450 GHz.
Difference between square wave and digital signal?
A: square wave can be positive and or negative. A digital signal is a square wave but it can be of invariable duty cycles
What does a microwave leak dector do?
It checks that no microwaves have escaped from the oven. Microwaves are harmful to living flesh. Not only will it cook you, as it does in the oven, but even small doses can cause eye cataracts. The door seal has a mesh, that will trap the microwave radiation. The mechanical size of the mesh is designed to interfere with the radio wave length. The door seals can get damaged with use and as radio waves are invisible, no one would know there is a problem. By moving a microwave leak detector around the door seal and cabinet, you can check to see that the oven is safe. The device can also be used for radar systems, that use wave guides up to the scanner, to check joints.
What is the relationship between radiowave and electromagnetic wave?
Actually, a radio wave is an electromagnetic wave( transverse, speed of 3.0x108, do not require a material medium to travel so can travel through a vacuum, carry no charge, can be produced and absorbed by matter and obey the laws of refraction and reflection) In the electromagnetic spectrum, radio waves have the longest wavelength and lowest frequency.
What is the difference between 60 htz and 120 htz?
the difference between 60Hz and 120 Hz is that. 60 hz wave will have wavelength of 0.016667 meter and change positive negative cycles 60 times in one second . while in 120Hz wave it can change positive and negative half cycles 120 times in a second and also has wavelength 8.333 mm
Is a microwave?
A short-wavelength radio wave. An electromagnetic wave that is somewhere in between regular radio waves and infrared radiation.
Is radio wave a light wave?
No, it is actually a microwave wave.
The main difference between a radio wave and a light wave is its?
Wavelength.
What is difference between shortwave and microwave?
a microwave is something that you warm your food with and a shortwave is water wave that are short
What type of electromagnetic waves are used for radars?
Microwave (portion of EM Spectrum lying between radio wave and infrared wave).
Describe a difference between radio and microwave signals?
"Radio" or "Radio Waves" are energy expended in the form of electro magnetic radiation. More specifically the term "Radio" refers to a specific frequency pattern of that radiation. This is how Radio broadcasting works. "Microwaves" are a said to be all radio frequency between 300Mhz and 30 Ghz. Thus microwave is a specific class of "Radio Wave". For more in depth explanations research the theroys of Heinrich Hertz.
What wave is used to broadcasting?
Radio waves and microwave.
What is the different between radio wave and electromagnet wave?
No difference at all. Radio waves are one of many types of electromagnetic waves.
What type of wave is microwave?
"Microwave" is an electromagnetic wave, and is part of the category of radio waves.A radio wave is "microwave" when its frequency is above 3 GHz (wavelength isless than 10 centimeters).Ironically, the "microwave oven" radiates the food with high power radio wavesat a frequency of 2.5 GHz, so technically, it doesn't use 'microwave' energy at all.
Do Radio waves run microwave ovens?
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.
What is the difference between microwave and an AM signal?
The primary difference is that the microwave signal is of a much higher frequency than an AM signal, if that AM signal is speaking to AM broadcast radio. In general, AM, or amplitude modulation, is not generally used as a modulation technique on microwave frequencies because there are other ways to put a signal on a microwave carrier that allow more information to be transmitted. AM is "low frequency" RF, while FM is a bit higher on the radio frequency spectrum, and microwaves are further on up.
Why microwaves are electromagnetic wave?
Because the label we give to radio waves whose frequency is between 3GHz and 300 GHz is "Microwave".
