How Does a Microwave Work? , A microwave bombards food with waves of energy, causing water molecules in food to vibrate and heat up. These waves, which only affect polar molecules, can pass transparently through most cooking vessels. The resulting heat or steam cooks the food much faster than traditional cooking. This is because the heat comes from everywhere in the food at once instead of working its way in from a heating el...Read more≫
