The first is a conceptual mistake. Light waves, as the name implies, have the heat of light! It takes a long time to heat with electric heating tubes, and old machines also use stainless steel brackets.

Microwave uses water molecules to rub at microwave frequency (2450M hz per second), so the heating time is short, but the moisture of food is greatly reduced, so it is better to hold it with tin foil paper.

Roasted chicken legs are usually wrapped in tin foil, heated for 40 seconds, and then roasted with light waves for one and a half minutes. Be careful! ! !
