How Does a Microwave Oven Work? Is It Safe To Use?

You might have a question in your mind that how doesmicrowave oven work? knowing about it is really important before buying it…

Microwave ovens were life-altering from the moment they began humming and heating in homes of the 1970s.

It quickened the process of cooking and reheating meals, saving time and increasing the potential for leisure overwork.

The users of Microwave Oven 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 oven?

So, How it works?

Microwave ovens cook foods by injecting them a form of energy called microwaves.

These electromagnetic waves are invisible to the naked eye and fall between radio waves and infrared waves. Radio waves have longer wavelengths whereas infrared rays have shorter wavelengths.

Inside the guts of a microwave, a device known as a magnetron, channels electrical energy from a power outlet to a heated filament, creating a movement of electrons that in turn transmits microwaves into the cooking chamber through an antenna.

Microwaves bounce around within the chamber and cook meals through radiation by heating—exciting molecules within an object—by becoming lodged in water, sugars, and fats.

As a result of the microwaves can travel only so far into an object before losing momentum, the outsides of thicker foods get heated by microwaves, and the inside of the foods 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, making them prone to melting, dissolving, and therefore contaminating the food cooked on or in them.

Metal reflects microwaves and therefore interferes with the movement of the waves inside the ovens.

And stirring food, at least that which can be stirred helps to spread the heat, ensuring that the inside is cooked as well as the outside.


Using a Microwave oven is a good choice as cooks the food quickly and saves your time, but you should take all the safety measures while using it.

There are many types of microwave oven that are available, and their uses range from basic cooking to advanced cooking. You can check it out on my blog.
