Microwaves are a form of electromagnetic radiation with wavelengths ranging from about 1 millimeter to 1 meter. They are commonly used in microwave ovens for heating and cooking food due to their ability to agitate water molecules, causing them to produce heat. Microwaves are also used in telecommunications, radar, and medical treatments.
