Microwaves work by emitting electromagnetic waves that generate heat, causing the water molecules within food or other substances to vibrate rapidly. This rapid vibration creates thermal energy, which raises the temperature of the object being heated. The high temperatures generated by microwaves can destroy many types of microorganisms, including bacteria and germs, by denaturing their proteins and disrupting their cellular structure.
