Microwave-oven-wavelength, the microwave radiation of microwave ovens and some radar applications is produced by a device called a magnetron.modern microwave ovens operate at the frequency 2,450 mhz.. Consumer ovens work around a nominal 2.45 gigahertz (ghz)—a wavelength of 12.2 centimetres (4.80 in) in the 2.4 ghz to 2.5 ghz ism band—while large industrial/commercial ovens often use 915 megahertz (mhz)—32.8 centimetres (12.9 in)., i found that in a typical microwave oven, the frequency is about 2450 mhz. using the formula, velocity = frequency x wavelength and knowing that the velocity of an electromagnetic wave is about 3.0 × 10 8 m/s, gives a wavelength of about 12 cm. in many ways, microwaves resemble radio waves but they are more difficult to generate..
The radiation used in microwave ovens is not resonant for water molecules and industrial microwave ovens use 915 mhz (probably, because larger cavities can produce more power). the frequency of 2.45 ghz is chosen because it falls in one of the bands not reserved for communication purposes., a microwave oven works by passing microwave radiation, usually at a frequency of 2450 mhz (a wavelength of 12.24 cm), through the food. water, fat, and sugar molecules in the food absorb energy.... Frequency = velocity / wavelength this gives f = (3 x 10 ^ 8) / 0.125 = 2.4 ghz or 2,400,000,000 hz. microwave ovens actually operate on 2.45 ghz, a wavelength of 122 millimetres, or 12.2 cm. login..., cooking with microwaves. microwaves are produced inside the oven by an electron tube called a magnetron. the microwaves are reflected within the metal interior of the oven where they are absorbed ....
The prefix micro- in microwave is not meant to suggest a wavelength in the micrometer range. rather, it indicates that microwaves are "small" (having shorter wavelengths), compared to the radio waves used prior to microwave technology., microwaves and wi-fi use the same unlicensed spectrum. in 1947 the international telecommunication union established the ism bands, short for industrial, scientific, and medical. the goal was to define what devices would be allowed to run at certain bands of radio frequency so that they wouldn’t cause interference with other radio communication services..
Remember that when it comes to emf radiation, the inverse-square law tells us that as we double our distance from the source of emf radiation, we quarter our exposure to it. the more distance the better. as a general rule try to stay at least 5-10 feet away from your microwave while its running.
