In a microwave, energy is transferred through electromagnetic radiation in the form of microwaves. These microwaves penetrate the food and cause the water molecules inside to vibrate rapidly, creating friction and generating heat, which cooks the food.
In a microwave oven, energy is transferred from the emitter (which is technically a klystron) to the water molecules in the item being heated, which have a resonant frequency equal to that of the microwave emission.
The microwave undergoes a variety of energy transformations when you are heating food. Starting from electrical energy (obtained via the mains power point/wall socket), the energy is transformed into microwave/thermal radiation (electromagnetic radiation/energy). These 'microwaves' react with the water particles in the food and cause them to vibrate. The friction produced by these vibrations produces heat and ultimately cooks/heats up your food. However, there is some energy that is transformed into light (the light you see when the microwave is one), sound (that humming noise you hear when it's operating) and kinetic energy (the rotating disk inside the microwave). Energy is transformed from electrical to heat, sound and light (if the microwave has a light). Energy is transferred to the food via the process of convection.
The microwave energy in a microwave oven is of a much lower frequency than light, but light is electromagnetic energy like the microwave radiation is.
In a microwave oven, electromagnetic waves are generated by a magnetron. These waves penetrate food and cause water molecules to vibrate rapidly, generating heat through friction. This heat is then transferred to the rest of the food, cooking it evenly and quickly.
In solids, energy is transferred through vibrations of particles called phonons. In liquids, energy is transferred by the movement of particles through convection and diffusion. In gases, energy is transferred mainly through collisions between gas molecules. In a vacuum, energy is transferred through electromagnetic radiation.

The electricity (electromagnetic energy) that drives the microwave oven is routed to the magnetron, which generates the microwave energy. (The electricity and microwave energy are both forms of electromagnetic energy.) The microwaves travel through a waveguide into the cavity (the cooking space) in the oven, and used to excite chemical bonds in the food items. This is a conversion of microwave energy (electromagnetic energy) into the mechanical energy of heat.

The type of energy conversion for a microwave is the transformation of electrical energy into light energy. This device works by focusing microwave light on the food inside of it.
