How 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
Mode Mixer | Magnetron | Ceramic | Bottom |

Microwaves are like TV waves or light waves You can’t see them, but you can see what they do
MIcrowaves pass through glass, paper and plastic wtth- out heating them so food ab- sorbs the energy Microwaves bounce off metal pans so food does not absorb the energy
Oven Cavity
A magnetron In the mlcro- wave oven produces micro- waves The microwaves move Into the oven where they are scattered or stirred by a mode mixer (IIke a fan) Microwaves 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 This IS one of the rea- sons for letting some foods (roasts, baked potatoes] stand for a while after cook- tng, or for stlrrlng some foods during the cooklng time
Metal Floor
The ceramic bottom of your mlcrowave oven lets micro- waves through Then they bounce off a metal floor, back through the ceramic bottom and are absorbed bv the food
