Microwave-oven-frequency-hz, the unit of frequency is a hertz (hz). velocity is a vector concept that deals with the direction and speed of an object. i found that in a typical microwave oven, the frequency is about 2450 mhz.. 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., 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..

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., it has little to do with the resonance of the water molecule and everything to do with the wavelength at the two frequencies: @ 2.45 ghz)2450 mhz) = 12.2 cm; 2 915 mhz = 33 cm - these are free-space wavelengths - the wavelengths in air or vacuum, i.e. the inside of a microwave oven (but not the food, where they are much shorter)..

Microwave ovens operate at a frequency of 2.45 ghz (2.45x10 9 hz) and this is not the resonant frequency of a water molecule. this frequency is much lower than the diatomic molecule resonant frequencies mentioned earlier., the uhf band has a frequency range of 300 mhz to 3 ghz, and is used for everything from tv broadcasting and gps to wi-fi, cordless phones, and bluetooth. frequencies of 1 ghz and above are also called microwave, and frequencies ranging from 1–6 ghz are often said to be part of the "sub-6 ghz" spectrum. frequency determines 5g speed & power.
