How Your Microwave Oven Works
Glau turntable
Metal fkkr
Microwave ovens are safe. Microwave energy is
not hot. lt causes fond to make its own heat, and
it’s this heat that nooks the food.
Microwaves are like TV waves or light waves.
;T cannot see them, but you can see what they
A magnetron in the microwave oven produces
microwaves. The microwaves move into the oven
where they contact food as if turns on the glass
turntable.
The glass turntable of your microwave oven lets
microwaves pass through. Then they bouncs off
a metal floor, back through the glass turntable
and are absorbed by the food.
Microwaves pass through most glass, paper and
plastics without heating them so food absorbs the
energy. Microwaves bounce off metal pans so
food does not absorb the energy.
Microwaves may not reach the center of a roast.
The heat around the outside is what cooks the
roast all the way through. This is one of the
reasons for letting some foods (roasts, baked
potatoes) stand for a while after cooking, or for
stirring some foods during the cooking time.
The microwaves disturb water molecules in the
food. As the molecules bounce around bumping
info each other, heat is made, like rubbing your
hands together. This is the heat that does the
cooking.
