IN Microwave there is no heating element instead of it has a magnetron which produces alternating energy waves by using electric energy and this energy waves increase KE of water molecules and thus by KTG its temperature increases and in this way food gets cooked

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.

Microwave ovens cook food by generating inter-molecular friction between the molecules of the food. The microwaves cause water molecules to vibrate; the increased friction between the molecules results in heat.

Microwave ovens are so quick and efficient because they channel heat energy directly to the molecules (tiny particles) inside food. Microwaves heat food like the sun heats your face—by radiation.
