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
Magyetron
Bottom
/
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
Using your lower oven
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.
