OPERATING PRINCIPLE
Microwaves used for cooking are
electromagnetic waves. They are
commonly found in our environment in
the form of radio waves, light and infra-
red rays.
Their frequency is in the 2450MHz
range.
Their behaviour:
· They are reflected by metals.
• They pass through all other
materials.
• They are absorbed by water, fat
and sugar molecules.
When food is exposed to microwaves its
molecules begin moving rapidly, causing
it to heat up.
The depth of penetration of the waves
into the food is about 2.5 cm, if the food
is thicker, cooking the centre of it is done
by conduction just like traditional
cooking.
In essence microwaves are simply
causing a thermal change inside the
food and are therefore not harmful to
health.
