What is the difference between radio frequency and microwave?
Radio frequencies include microwaves, which are about 2.5 GigaHertz. Microwaves are at the very high frequency end of radio frequencies.
RF means radio frequency or relativity low range of frequency microwaves however are into the top range of the spectrum or very hi frequency.
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… Read More
"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.
"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.
a microwave requires a much higher frequency
Microwaves are radio waves. They're both the same exact physical phenomenon as light, heat, x-rays, and visible light. The only difference among all of these is their wavelength (frequency).
Is the frequency of radiation used in a microwave oven higher or lower than that of your favorite FM radio station broadcasting?
Much higher. The carrier frequency of your favorite FM radio station is between 88 and 108 MHz. The frequency of the radiation inside the microwave oven is close to 2,145 MHz.
Microwave transmission is a high-frequency radio wave transmitted through the air. Fibre-optic cables are a very thin glass fibre along which infra-red or laser light is transmitted.

A: AM radio is an Amplitude Modulation transmission . Meaning it has fix frequency but it is modulated by the signal. FM Frequency Modulation the frequency is modulated by the signal
Hi! Microwave frequency is the top end of the radio wave frequencies. The radio wave frequency is part of the electromagnetic spectrum (EM spectrum) - and there the frequencies carry on up to infra red ... blue light ... etc. Mike p.
"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 is less than 10 centimeters). Ironically, the "microwave oven" radiates the food with high power radio waves at a frequency of 2.5 GHz, so technically, it doesn't use 'microwave' energy at all.
Frequency of the wave. X-rays are higher frequency.
Because the label we give to radio waves whose frequency is between 3GHz and 300 GHz is "Microwave".
A microwave oven is called a 'microwave' because that is the type of radio wave it uses to induce heat. An RF wave with a frequency between 300 MHz and 300 GHz is considered a microwave. Microwave ovens typically operate around 1-2 GHz. It is always surprising as to why they are called micro waves when their frequency is in Giga range. Its because, their wavelength is in micron range.
What is the difference between microwaves used to cook food and microwaves used for transmitting information?
No fundamental difference at all. Microwave cooking ovens are assigned their own operating frequency ... 2.45 GHz in the USA ... and they all operate at that frequency, whereas microwave communication goes on in several different frequency bands. Also, the cooking ovens use far more transmitting power to do their job. A typical microwave oven pours 1,000 to 2,000 watts of "cooking power" (RF power) into the chamber where you put the meatloaf, whereas microwave… Read More
-- A 'microwave' is a radio wave at any frequency above 3 GHz. -- A 'microwave oven' cooks with radio waves from a high power source at 2.450 GHz.
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.
Radio frequency waves are alternating currents. Many people assume that alternating current means only household supplies. Not so. The only difference between the two is the frequency : 50 or 60 Hz for house supply, anything from 16 KHz up to 100 MHZ for radio.
They are the same thing; vibrations of the electromagnetic field. Microwaves have a frequency between 0.3 GHz to 300 GHz, and radio waves have a frequency between 3 Hz to 300 GHz. So microwaves are a type of radio wave.
The electromagnetic frequency they are designed to observe.
The "microwave" range of radio waves is defined as frequencies between 3 - 300 GHz. But the question says " a " microwave, so we suspect it's talking about the box you use to heat the leftover meat loaf. The microwave oven operates in the Industrial/Scientific/Medical frequency band, at or near 2,450 MHz. (So, technically, it isn't a 'microwave' at all, since that frequency is below the range defined as 'microwave'. Guess it should be… Read More
They terms frequency are essentially the same, except radio waves are electromagnetic, and acoustic waves are pressure waves. An audio frequency is a range of frequencies that we can hear, approx up to 20Khz, anything past 20Khz is said to be radio waves
There is no difference. Microwaves are radio waves with any frequency above 3 GHz.
In round figures 1 Km (AM broadcast radio) to 0.1 mm (microwave).
Radio allows audio broadcast whereas TV allows both audio and video broadcast. Both makes use of radio waves however their frequency is different. Radio can use FM or AM frequency range.
Microwave radio require free line of sight between point A and B. Any obstruction in the first Fresnel zone (imaginary ellipsoid zone between point A and B) will degrade the availability. Furthermore, rain attenuation is affect the transmission in frequency above 10GHz.
A radio wave has a longer wavelength and a lower frequency, compared to a light wave.
It is radio waves, at the frequency of 2.45 GHz, and very high power.
Microwaves are radio waves. Most satellites communicate in microwave radio frequency bands.
a microwave is an electromagnetic wave. ================ Answer #2: A microwave is a radio wave with a wavelength less than 10 cm (frequency greater than 3 GHz).
Audio frequency describes the frequency of longitudinal waves (pressure waves) in air or water and can be sensed directly by the human ear. Radio frequency describes the frequency of transverse electromagnetic waves by which radio signals are transmitted. These waves cannot be sensed by people and must converted to audio signals by manufactured devices before people can hear them.

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… Read More
The numbers in an FM radio station represent the frequency the station transmits the signal on. The frequency range for FM band radio stations is from 87.5 MHz to 108.0 MHz. These radio frequencies are considered VHF or Very High Frequency. The difference between AM and FM radio is that in AM radio the Amplitude is Modulated, or changed to send the signal, whereas with FM, the Frequency is Modulated or altered to send the… Read More
"Microwave" is the official label for radio between 3 GHz and 300 GHz. That frequency range corresponds to wavelengths from 1 millimeter to 10 centimeters.
Microwave frequency radio waves are usually produced by a MAGNETRON.
The difference between a radio wave and a x-ray is the fact that x-rays have a much higher frequency. Since higher frequency means more energy in electromagnetic waves, x-rays can be used for purposes such as taking photos of things inside the body. Radio waves are at a lower frequency and have a much longer wavelength. They are used in radio, television, and communication.
The formal definition of "microwave" is any frequency greater than 3 GHz. (Wavelength less than 10 centimeters.) Frequency bands allocated for microwave radio communication in the US are found in the neighborhoods of 6, 11, 13, 18, 23, 24, 27, and 38 GHz. Note: It looks like the the formal definition of "microwave" doesn't include microwave ovens ... they operate at 2.45 GHz.
"Microwave" IS radio waves. They're called microwaves when their frequency is 3 GHz or higher.
"Microwave" is the loose term used to describe the higher-frequency portion of the general category of radio waves. The closest thing to a formal definition says that "microwave" is anything with a frequency higher than 3 GHz (wavelength less than 10 centimeters).
Microwaves are radio waves. In the case of microwave ovens, the commonly used radio wave frequency is roughly 2,500 megahertz (2.5 gigahertz). Radio waves in this frequency range have an interesting property: they are absorbed by water, fats and sugars. When they are absorbed they are converted directly into atomic motion -- heat. Microwaves in this frequency range have another interesting property: they are not absorbed by most plastics, glass or ceramics. Metal reflects microwaves… Read More
The difference between the Narrow Band radio frequency (nbfm) and the Wide Band radio frequency (wbfm) is that Narrow Band provide a higher quality of sound but has fewer channel available to use whilst Wide Band provides a lower quality of audio but has a much larger range of channels available.
They are used for communications and, if the frequency is high enough, for heating food in a microwave oven.
Radio wave frequency and microwave radiation are both forms of energy called electromagnetic radiation?
The answer is yes.
Radio energy, at a frequency of 2.5 GHz.
The question is somewhat unclear. I'm going to assume that it's asking "What is the radiation that cooks the food in a microwave oven ?" The microwave oven uses a cavity magnetron to generate high power radio waves at the frequency of 2.45 GHz. For comparison ... -- Various models of microwave ovens guide anywhere between 600 to 2,000 watts of radio-wave power into the chamber where you put the meatloaf. -- Microwave radio transmitters… Read More
