The defrost mode of a microwave oven turns the microwaves on and off repeatedly to reduce the power. Reducing the power reduce the chance of one part of the food becoming hot while other parts are still frozen.

Is cooking food using a microwave oven an example of radiation?
Yes, since the oven heats food by irradiating it with microwaves. Microwaves are an example of electromagnetic radiation, having a frequency lower than that of visible light.
How are microwaves helpful in your lives?
Microwaves can be used to send signals or to cook food.
Are microwaves safe?
Microwaves aren't safe, but microwaved food is.
How do microwaves affect the water?
microwaves vibrate water molecules in food to create heat
What waves can cook food?
Microwaves.
What does it mean when a microwave oven uses convection microwaves?
A convection microwave uses both microwaves and convection heating to cook the food. The convection cooking allows the food to be browned and cooks the outer part of the food while the microwaves cook the interior of the food.
What kind of waves can cook food?
Microwaves
What is one use for microwaves?
To warm food.
Can microwaves cook food from the inside out?
no the microwave can not cook food from the inside out.
What ubstance in the food absorbs the microwaves?
Water molecules in the food. Microwaves work by only vibrating the water molecules, in order to increase the temperature of the food without significantly altering the properties of the food itself.
How microwaves cook food?
the microwave makes the water molecules in the food move and bump around this causes friction in the food to be cooked.
Can you heat food in an metal container in a microwave?
No, the metal will reflect the microwaves and damage the magnatron (the part that produces the microwaves).
