Question

How do microwaves heat food so quickly?

Answer 1

Microwave ovens use radio waves at a specifically set frequency to agitate water molecules in food.

As these water molecules get increasingly agitated they begin to vibrate at the atomic level and generate heat.

This heat is what actually cooks food in the oven.

Because all particles in the food are vibrating and generating heat at the same time, food cooked in the microwave cooks much faster than food cooked in a conventional oven where heat must slowly travel from the outside surface of the food inward due to the resistance.
