OW YOUR MICROWAVE OVEN WORKS
Microwave ovens are safe. Microwave energy is
not hot. It causes food to make its own heat, and
it's this heat that cooks the food.
Microwaves are like TV waves or light waves. You
cannot see them, but you can see what they do.
A magnetron in the microwave oven produces
microwaves. The microwaves move into the oven
where they contact food as it turns on the turntable.
The glass turntable of your microwave oven lets
microwaves pass through. Then they bounce off a
metal floor, back through the glass turntable, and
are absorbed by the food.
