Want this question answered?
The frequency at which a microwave oven operates, about 2,450 MHz, has a wavelength of about 12 cm.
10 centimeters or less If you mean "microwave oven", those operate at the frequency of 2.45 GHz, where the wavelength is 12.24 centimeters.
"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.
Microwave ovens operate at about 2,450 MHz.
The microwave energy in a microwave oven is of a much lower frequency than light, but light is electromagnetic energy like the microwave radiation is.

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.
Wavelength = (speed) / (frequency)Speed of light/radio/microwave = 3 x 108 meters per secondWavelength in the microwave oven = (3 x 108) / (2.4 x 109) =0.125 meter12.5 centimeters125 millimeters125,000,000 nanometersabout 4.9 inches
A microwave oven incorporates a microwave generator which produces EM energy at the right wavelength or frequency to energise water molecules in the food being cooked, which produces thermal energy in the food. The microwaves don't escape from the oven because they don't penetrate the materials the enclosure is made from. (EM = electromagnetic)
There should be a note somewhere on the oven stating the frequency of the waves produced. It's normally around 2.5gigahertz. You can use this to workout the wavelength. The speed of the microwaves is the same as the speed of light, 3x10 to power of 8 metres per second. To get the wavelength you divide the speed by the frequency; 300 000 000m/s divided by 2 500 000 000waves/s which gives 0.12metres or 12cm.
