How Do Microwaves Work?
Microwave ovens were life altering from the moment they began humming and heating in homes of the 1970s. The sprinter to the conventional oven’s cross-country runner, microwaves quickened the process of cooking and reheating meals, A___________. The mechanics of the microwave were, from the very start, mysterious. It seems to be a magical metal box B___________ rather than heating the air and everything around it by conduction from a flame (as was the norm). Microwave users also came to accept the odd rules of the technology: no metal, no meltable plastics, and stir to cook evenly. So what is the magic behind the microwave?
Microwave ovens cook foods by injecting them with, surprise, microwaves — a form of energy. These electromagnetic waves are invisible to the human eye and fall between C___________. Inside the guts of a microwave, a device called a magnetron channels electrical energy from a power outlet to a heated filament, D___________. Microwaves bounce around in the chamber and cook food through radiation heating — exciting molecules within an object — by becoming lodged in water, sugars, and fats. Because the microwaves can travel only so far into an object before losing momentum, E___________, and the insides are heated subsequently by the conductive transfer of heat from the outsides.
So how do the common microwave rules make sense with these mechanics? Certain types of plastics are able to absorb microwaves like foods do, F___________. Metal reflects microwaves and therefore interferes with the movement of the waves inside the ovens.
- creating a flow of electrons that in turn transmits microwaves into the cooking chamber through an antenna
- saving time and increasing the potential for leisure over work
- radio waves, which are longer in wavelength, and infrared waves, which are shorter
- the outsides of thicker foods become heated by microwaves
- making them prone to melting, dissolving, and therefore contaminating the food cooked on or in them
- ensuring that the inside is cooked as well as the outside
- that spins and heats food by invisible means
