Microwave oven is a Group 2 ISM equipment in which radio frequency energy is intentionally generated and used in the form of
electromagnetic radiation for the treatment of material . This oven is a Class B equipment suitable for use in domestic
establishments and in establishments directly connected to a low voltage power supply network which supplies buildings used for
domestic purposes

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 .
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
4-5 cm and as heat spreads through the food by conduction ,
just as in a traditional oven , the food cooks from the outside
inwards .
In a microwave oven ,
electricity is converted into
microwaves by the
MAGNETRON
.
The microwaves bounce
off the metal walls and the
metal door screen
