How Do Microwaves Work microwave oven Microwave ovens don’t operate in the same manner as conventional ovens. So how do microwaves work then? Microwave ovens take advantage of the behavior of water molecules when subjected to electromagnetic waves found in the microwave band. To understand how this happens, we’ll have to comprehend the basic properties of water molecules and microwaves (the electromagnetic waves, not the oven). The mickey mouse-shaped water molecule is actually a dipole. Microwaves used for cooking, on the other hand, are electromagnetic waves possessing frequencies around the 2.45 GHz range. That is, when a positively charged particle is exposed to an electric field, it experiences a force (due to the field) pointing in the direction of the field. Now, since an electromagnetic wave (like the microwave) is made up of alternating electric fields, a charge exposed to it will experience forces regularly changing in direction. Avoid putting in metal into the microwave oven while heating. Related
