HOW MICROWWE OVENS WORK
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 can’t see them, but You can see what thev do
Mrcrowaves pass through glass, paper and plastrc without heatrng them so food absorbs the energy Micro- waves bounce off metal pans so food does not cbsorb the energy
Oven Cavity
A magnetron produces micro- waves. The mrcrowaves move Into the oven where they are scattered around by a stirrer (like a fan)
Mrcrowaves bounce off metal oven walls and are absorbed by food
Microwaves may not reach the center of a roast The heat around the outside IS what cooks the roast all the way through Thus IS one of the reasons for lettrng some foods (roasts, baked pota- toes] stand for a while after cookrng. or for stirring some foods durrng the cooking time
Metal Floor
The bottom of your micro- wave oven lets micro- waves through. Then they bounce off the metal floor, back through the bottom, and are ab- sorbed by the food.
The mrcrowaves disturb water molecules in the food As the molecules bounce around bumping Into each
other, heat is made, like rub- bing your hands together. This IS the heat that cooks.
