Microwaves how do they cook food

I think that this is a very interesting process that I only knew part about. I also think that it should be more complicated than the process stated above but it's not. When I took my family consumer science class, they taught us all about how microwaves are used to cook food. Its a neat process.

Its ironic isn't it the average person uses a microwave at least one a week but has no idea how it works. That is how it goes with most technology such as the internet you use it but do you really understand it.

If more people know how you use the devices in there home there would be much less problems. The person who invented the microwave was named was Percy Spencer and his invention was an accident!

Spencer worked for a company named Raytheon, developing microwave radar transmitters during World war 2 One day in , he noticed that a candy bar he had in his pocket was starting to melt. The microwaves from the radar set he was working on were cooking the candy bar in his pocket! With a little experimentation, Spencer figured out that the microwaves could be concentrated to heat food. He created the first working microwave oven, and the first food he cooked in it was popcorn.

This is another thing that I never really thought about. Mobile Newsletter banner close. Mobile Newsletter chat close. Mobile Newsletter chat dots. Mobile Newsletter chat avatar.

However, if an oven does continue to operate with the door open, consumers cannot be percent sure that microwave radiation is not being emitted. Thus, if this occurs, the FDA recommends immediately discontinuing use of the oven.

If you suspect a radiation safety problem with your microwave oven, you may contact the microwave oven manufacturer. Manufacturers who discover that any microwave ovens produced, assembled, or imported by them have a defect or fail to comply with an applicable Federal standard are required to immediately notify FDA.

You may also report any suspected radiation-related problems or injuries to the FDA by completing and mailing the Accidental Radiation Occurrence Report form. What is Microwave Radiation? Cooking with Microwaves Microwaves are produced inside the oven by an electron tube called a magnetron. Avoiding Injuries from Super-Heated Water in Microwave Ovens The FDA received reports in the past of serious skin burns or scalding injuries around people's hands and faces as a result of hot water erupting out of a cup after it had been overheated in a microwave oven.

Microwave Ovens and Health Microwave radiation can heat body tissue the same way it heats food. Microwave Ovens and Pacemakers At one time there was concern that radiation leakage from microwave ovens could interfere with certain electronic cardiac pacemakers. Checking Ovens for Leakage and Other Radiation Safety Problems There is little cause for concern about excess microwaves leaking from ovens unless the door hinges, latch, or seals are damaged. How to Report Microwave Oven Radiation Safety Problems If you suspect a radiation safety problem with your microwave oven, you may contact the microwave oven manufacturer.

Tips on Safe Microwave Oven Operation Follow the manufacturer's instruction manual for recommended operating procedures and safety precautions for your oven model. Use microwave safe cookware specially manufactured for use in the microwave oven. Don't operate a microwave oven if the door does not close firmly or is bent, warped, or otherwise damaged.

Stop using a microwave oven if it continues to operate with the door open. As an added safety precaution, don't stand directly against an oven and don't allow children to do this for long periods of time while it is operating. Some ovens should not be operated when empty. Refer to the instruction manual for your oven. Regularly clean the oven cavity, the outer edge of the cavity, and the door with water and a mild detergent. A special microwave oven cleaner is not necessary.

This bending from the solid state magnet causes the electrons to fly in a sort of loop. In a grander scale, as these electrons being sent out from the filament and flying in loops, microwaves are created. Essentially, the looping electrons fly past anode terminals continuously.

As an electron flies past an opening between anodes, it creates a microwave. Think of it as blowing across the open end of a bottle. Understanding how a microwave oven or more specifically, a magnetron, creates microwaves is key, but how do these waves then heat up your hot pockets?

Well, the microwaves are transmitted from the magnetron through an antenna. The microwaves then bounce around the inside of the metal casing of the microwave in different patterns. These waves are then easily absorbed by the water molecules in food.

Molecules absorb the wave which causes them to start to vibrate, converting the energy into heat. This is also the core principle behind microwave safe materials. Digging deeper into why the absorption of the microwave by water molecules causes the food to heat up, we have to look into electric fields. Water molecules, just like magnets, are positively charged on one side and negatively charged on the other.
