If you mean "microwave oven", those operate at the frequency of 2.45 GHz,
where the wavelength is 12.24 centimeters.
The frequency at which a microwave oven operates, about 2,450 MHz, has a wavelength of about 12 cm.
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.
A photon of this wavelength has an energy of about 10 ^ -5 eV.

'Microwave' is not a scientific term, and encompasses a wide range of frequencies. Wikipedia speaks of a range between 0.3 and 300GHz, resulting in a wavelength between one meter and one millimeter. Other interpretations of the colloquial term 'microwave' might exist. References:
Radio with mm to cm range wavelengths. It is longer wavelength than IR.
Microwaves are wavelengths of light that are shorter than radio waves, but longer than infrared light waves. The wavelength range is 1 meter to 1mm. One particular wavelength is optimum for being absorbed by water, and this is what "microwave ovens" are tuned to produce. This is 2.45 GHz, which is about 12.2cm wavelength.

The microwave spectrum stretches from about 0.1 mm to about 10 cm wavelength. In terms of the number of frequency doubles (think octave), this range is about 12.4 times the breadth of the visible light spectrum.
