How does a microwave exactly work?

Question

How?

Thx.

Serious answers please!!

Answer 1

It emits micro-waves, which then hit the food or item in it and shakes (moves) the particles around, when this happens the particles create friction which is then is heat. That's why only some dishes are microwave safe because they could melt and deform.

Answer 2

Rather like a whistle, actually. A whistle creates a standing wave in the whistle chamber. Sound is produced when the wave experiences diffraction as it hits the slit at the top of the whistle. A flute works the same way, although the size of the chamber can be varied, thus changing the pitch.

Microwaves themselves are a form of electromagnetic radiation somewhere between radio waves and infrared heat waves. They cause water molecules to vibrate faster, and molecular motion is basically what temperature is. Microwaves are the basis of radar systems. In fact the first use of microwaves for cooking was during the battle of London in the early 1940's. Long radar lines were maintained along the eastern British coast to warn of German bombing raids. It was found that steaks hung on the wire mesh radar dishes could be nicely cooked in a fraction of the time it took using ordinary means.After the war, the bombers were retrofitted to become commercial airliners and the radar technology was used in microwave ovens.

Answer 3

Microwaves are electromagnetic waves that used in a household microwave appliance heat items through dielectric heating where energy is absorbed in water, fats and sugar of the item that is being heated.
