Food and cookware taken out of a microwave oven are rarely much hotter than 100 Â°C (212 Â°F). Cookware used in a microwave oven is often much cooler than the food because the cookware is transparent to microwaves; the microwaves heat the food directly and the cookware is indirectly heated by the food.
Microwave heat sources. One of the most common uses of microwaves is to heat food quickly. Microwave ovens are possible because microwaves can be used to transmit thermal energy. The discovery of this phenomenon was purely accidental.icrowaves have frequencies ranging from about 3 billion cycles per second, or 3 gigahertz (GHz), up to about 30 trillion hertz (terahertz or THz) and wavelengths of about 30 centimeters (12 inches) to 3 millimeters (0.12 inches), although these values are not definitive.
