Microwave ovens operate at about 2,450 MHz.
In a microwave oven, radiofrequency electromagnetic waves are produced. These waves cause the water molecules in food to vibrate, generating heat through friction and cooking the food from the inside out.
Microwaves are electromagnetic waves with a frequency of about 2.45 GHz and a wavelength of about 12.2 cm; in the electromagnetic spectrum, they fall before infrared light but after radio waves (Heckert 2007). In a microwave oven, microwaves are produced by a device called a magnetron.-Google
The wavelength of a wave produced by a microwave oven is around 12.2 centimeters, corresponding to a frequency of 2.45 gigahertz. This wavelength allows the microwave radiation to penetrate and heat food evenly.
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.
The frequency range of a microwave oven is typically around 2.45 gigahertz (GHz).

It is radio waves, at the frequency of 2.45 GHz, and very high power.
Microwaves in a microwave oven are produced by a component called a magnetron, which converts electrical energy into electromagnetic waves that heat up food.
Microwave oven
The frequency range of a microwave oven is typically around 2.45 gigahertz (GHz).
A microwave oven uses microwave waves for cooking food.
microwave is an oven
A microwave oven uses electromagnetic waves to heat food by causing water molecules in the food to vibrate and generate heat from friction. These waves are produced by a device called a magnetron and are contained within the microwave oven cavity to effectively heat the food placed inside.
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 called a "UHF Oven".)
