2. Microwave oven - Wikipedia

   en.wikipedia.org/wiki/Microwave_oven

   Globally. A microwave oven or simply microwave is an electric oven that heats and cooks food by exposing it to electromagnetic radiation in the microwave frequency range. [1] This induces polar molecules in the food to vibrate [2] and produce thermal energy in a process known as dielectric heating. Microwave ovens heat foods quickly and ...
