Oven Cavity
A magnetron in the mrcro-
wave oven produces micro-
waves The microwaves
move Into the oven where
they ore scattered or stirred
by a mode mixer (like a fan)
Microwaves bounce off
metal oven walls and ore
absorbed by food
Mlcrowaves bass through
gloss, paper and plastic with-
out heating PIem so food ab-
sorbs the energy Microwaves
bounce off metal pans so
food does nc,t absorb the
energy
Microwaves may not reach
the center of a roast. The heat
around the outs/de
IS
what
cooks the roast all the way
through This IS one of the rea
sons for letting some foods
(roasts. baked potatoes)
stand for a while after cook-
ing or for strrrtng some foods
during the cooking time
Metal Floor
The ceramic bottom of your
microwave oven lets micro-
waves through Then they
bounce off a metal floor,
back through the ceramic
bottom and ore absorbed
by the food

The microwaves disturb
water molecules In the food.
As the molecules bounce
around bumping into each
other, heat is mode, like rub-
bing your hands together.
