What sound the Microwaves?
The microwaves are electromagnetic waves of high frequency very similar to the luminous waves or to those of the radio.
But, while the length of the above mentioned changes between one meter and several kilometers, the microwaves are much fellings alone they have less 12,5 cm long.
On the other hand although the microwaves produce heat in the stove, they penetrate only in the food and provide the necessary energy to them so that his water molecules begin vibrating.
The rapid vibrations of these molecules produce the extreme heat that serves to cook the food.
The Microwaves disappear on having opened the door of the kitchen.
