Radio wave at frequency of 2.45 GHz to cook the food.
Some units also use light waves from a light source to let you see
what's going on inside during the cooking.

What part of the electromagnetic spectrum is used in ovens?
In a microwave oven, we find that microwave energy (from the microwave portion of the electromagnetic spectrum) are used. In a conventional oven, gas or electricity is used to create infrared heat, so we find infrared radiation (from the infrared portion of the electromagnetic spectrum, which is just below the visible light or optical portion) used there. If the oven happens to be a combination microwave and conventional, we'll find both types of electromagnetic waves generated for use inside.
What does a microwave oven convert electrical energy into?
Into microwave electromagnetic radiation.
What kind of energy does a microwave oven use?
A microwave oven uses electrical energy (which is electromagnetic energy) from the mains, and it generates microwave energy (which is also electromagnetic energy) to heat/cook food items.
Is light energy used in a microwave oven?
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.
What energy changes occur in a microwave oven?
We find that in the microwave oven, electromagnetic energy (microwaves) are converted in thermal (heat) energy.

Which kind of oven operates on short electromagnetic waves?
Microwave oven
What parts of the electromagnetic spectrum do you use the most?
Quite simply, the Microwave Oven uses the Microwave part of the spectrum.
How does a microwave oven use the electomagnetic spectrum?
The standard microwave oven uses only a tiny portion of the electromagnetic spectrum that is centered on 2.45 GHz. That's 2.45 gigaHertz or 2,450,000,000 Hertz (cycles per second). Almost all of the energy the unit generates is right at that frequency.
What does a microwave oven convert electrical energy into?
Into microwave electromagnetic radiation.
A microwave oven converts electrical energy into what energy?
Into microwave electromagnetic radiation.
Is a microwave oven an example of electromagnetic energy?
Yes

We find that in the microwave oven, electromagnetic energy (microwaves) are converted in thermal (heat) energy.
What are the energy waves produced in a microwave oven?
The energy waves produced in a microwave oven take the form of electromagnetic radiation at about 2,450 MHz, which is in the microwave range.
How are micro waves produced?
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
