Microwaves are used for cooking food in microwave ovens.

Microwaves are easily absorbed by water molecules in food, causing them to vibrate more vigorously.

The microwave energy is changed to heat energy as it is absorbed, which cooks the food.

That's why foods that are high in water content, like fresh vegetables, can be cooked more quickly in microwave ovens.

Microwave cooking can be more energy efficient than conventional cooking because foods cook faster and the energy heats only the food, not the whole oven compartment.

Glass, paper or plastic containers are used in microwave ovens because microwaves pass through these materials.

Since the microwaves are not absorbed, they do not heat the containers directly.

However, they can become hot from the heat of the food cooking inside them.
