MICROWAVING PRINCIPLES

Microwave energy has been used in this country to cook and reheat food since early experiments with RADAR in
World War ll. Microwaves are present in the atmosphere all the time, both naturally and manmade sources. Manmade
sources include radar, radio, television, telecommunication links and car phones.

In a microwave oven,
electricity is converted
into microwave by the
MAGNETRON.
The microwaves bounce
off the metal walls and
the metal door screen.
The microwaves cause the water molecules to vibrate
which causes FRICTION, i.e. HEAT. This heat then
cooks the food. Microwaves are also attracted to fat and
sugar particles, and foods high in these will cook more
quickly. Microwaves can only penetrate to a depth of 1
- 2 inches(4-5cm) and as heat spreads through the food
by conduction, just as in a traditional oven, the food
cooks from the outside inwards.

cooking containers to be
absorbed by the water

foods contain water to a
more or lesser extent.
