What does radiation cooking rely on?

Radiation cooking utilizes the transfer of energy through waves of heat or light. This method does not require direct contact with a heat source, distinguishing it from conduction, where heat is transferred through physical contact, or convection, which involves the movement and circulation of hot air or liquid. Instead, radiation cooking depends on electromagnetic waves, such as microwaves or infrared radiation, to heat food. These energy waves penetrate the food and excite the molecules, causing them to heat up. This method is commonly used in appliances like microwave ovens and certain grilling techniques, making it an effective way to cook food quickly and evenly.
