Microwave oven - Wikipedia

A microwave oven (commonly referred to as a microwave) is an electric oven that heats and cooks food by exposing it to electromagnetic radiation in the microwave frequency range. This induces polar molecules in the food to rotate and produce thermal energy in a process known as dielectric heating.Microwave ovens heat foods quickly and efficiently because excitation is fairly uniform in the
