Microwaving Principles
Microwaves are present in the
atmosphere all the time, both
naturally and from manmade
sources. Manmade sources
include radar, radio, television,
telecommunication links and mobile
phones.

Base of
the oven
In a microwave oven, electricity is
converted into microwaves by the
Magnetron
. For bottom feeding,
please refer to page 40.
Transmission
Then they pass through the cooking
containers to be absorbed by the
water molecules in the food, all
foods contain water to a more or
lesser extent.
Reflection
The microwaves bounce off the
metal walls and the metal door
screen.
The dish used to cook or
reheat the food will get warm
during cooking, as the heat
conducts from the food. Even
in microwaving, oven gloves
are required!
Microwaves
can not pass through metal
and therefore metal cooking
utensils can never be used in
a microwave, for cooking on
microwave only.
