How the microwave oven works
A microwave oven is a cooking appliance that uses microwaves to heat food. Microwaves
are electromagnetic waves, just like radio and television waves. A radio converts these
waves into sound, whereas a microwave oven converts them into heat.
The heat arises because the microwaves cause water and fat molecules, that are always
present in food, to move quickly. The molecules slide past each other quickly and friction
occurs. This friction causes heat (try rubbing your hands together quickly).
The microwave oven heats food very intensively, because the microwaves penetrate the
food directly. The waves do not just heat the outside of the food, but get right inside the
food. Compared to conventional methods of cooking, with small quantities, the cooking
time is much shorter.
