ABOUT YOUR MICROWAVE
Microwaves are high-frequency electromagnetic waves similar to radio
waves. While radio waves may vary in length from one metre to many
kilometres, microwaves are very short (less than 12.5 centimetres).
The microwave oven will work using an ordinary household electrical
socket. Inside the microwave oven is the magnetron, which turns the
electrical energy into microwaves.
Microwaves cannot go through metal, so the inside of the oven is
lined with metal. The door is lined with a fine metal mesh which stops
microwaves getting through. This means that when the microwave
oven door is shut, there is no possibility that microwaves can be
released.
Microwaves do not make any heat themselves but cause water
molecules in food to vibrate.
This vibration produces heat that cooks the food. This is why your
food will come out of the microwave piping hot, when your utensils
inside the oven stay much cooler. The microwaves do not stay in the
air or in the food when you open the microwave oven door.
