An Introduction To Microwaves

Microwaves are low on the electromagnetic spectrum. The electromagnetic spectrum is a range of all the possible electric radiation. Frequency of a wave is the number of waves per second and the frequency of a microwave is between 300 MHz and 300 GHz. The wavelength of a wave is the distance from one peak of a wave to the peak of a following wave and a wavelength of a microwave varies from one millimeter to thirty centimeters. The frequencies range from ultra high frequency to super high frequency to extremely high frequency.

The microwave was discovered by Heinrich Hertz and predicted by James Clerk Maxwell. In 1864, James Clerk Maxwell theorized about microwaves until he predicted equations that would prove the existence of microwaves. In 1888, Heinrich Hertz took these equations and used them in an experiment. He made an apparatus that produced waves and detected these waves. The experiment displayed the different wavelengths of certain waves, such as the short wavelength of microwaves. The discovery of microwaves permitted it to be used for commercial purposes.

Microwave ovens are the best example of a commercial usage of microwaves. Microwave ovens use microwaves at a frequency of 2450 MHz. The Microwaves travel and cause the water, fat, and sugars to vibrate resulting in the food’s temperature rising. This type of energy is called Dielectric energy. This benefits the food making process and anyone who buys TV dinners. Another instance of microwaves is cell phones. Cell phones use an antenna and a little transmitter to connect to the microwaves emitted in the air. To make cell phones more attractive for buyers, they minimized the transmitters and antennas.

The microwaves used in phones make it possible for a person to receive calls from any location, this is especially important in emergencies. Broadcasting transmissions, such as cable TV and the Internet, use microwaves to transmit the signal in order to broadcast. These two sources that use microwaves permit faster communication between all areas of the world. These two sources that use microwaves are the most popular ways of entertainment for most of the United States. The commercial industry benefits from these products that use microwaves.

Current studies prove indecisive about the effects of microwaves. Microwave ovens can cause damage to the eyes. If a person were to press their face on the microwave oven, it can cause cataracts in the eyes. The best advice to protect against this effect is to stay a couple feet away according to Dr. Joseph Mercola. The most controversial issue about microwaves is if they have a hazardous effect on the brain through cell phone usage. Some people believe that having a mobile phone near the ear for a prolonged period of time will cause cancer, or a brain tumor due to the microwaves that are transmitted. According to the article “MIRROR, MIRROR, Fearing Rads, Cell Addicts Sprout Wires” in The New York Times, “No studies directly link cell phone use to brain cancer…” A piece of advice that most doctors would give to patients concerned with the microwaves form their cell phones is to only use it when necessary. However, studies have not proven anything that is accurate at this point in time, they are still in the process of being conducted.

Microwaves allow the world to progress. They help people communicate faster and more effectively. Experiments are still continuing to figure out the real dangers of these waves. Microwaves are one of the most used waves for commercial uses. Microwaves surround our everyday activities.

Why you should choose a Convection Oven over a Conventional!

Convection ovens use a specially designed fan that forces the hot air inside them to circulate around the food that’s being cooked! For years they were mainly used in restaurants, buy now they can also be found in thousands if not millions of home kitchens!

What makes them better than conventional ovens, is the fact that they cook faster and they can make make crispier, perfectly browned foods!

Convection oven vs. Conventional oven

A convection oven is usually equipped with a heating element in its rear, just like a conventional oven. What sets convection ovens apart though, is the fact that they also feature a specially designed fan that helps circulate the warm air inside them, which results in much faster and more uniform cooking!

The heat in a conventional oven, will rise upward, toward the food which often causes hot and cold spots to appear in the food, even if it appears to have been cooked to perfection!

There is a wide variety of convection oven recipes available on line and on special cooking books, however, you can also use convection ovens to cook regular recipes! You’ll just have to decrease the temperature of the oven by 25 to 50 degrees!

Why Use Toaster Oven

There are a lot of people who think that normal or ordinary ovens are quite obsolete as well as redundant. This is because of the fact that the modern age is said to be the age of new fangled and latest microwave ovens that seem to be all over the marketplace. While this may be true and many people may be enamored with microwave cooking, there are lots of people who still love to use the good old Toaster Oven that has a set of unique characteristics as well as benefits that are associated closely with it. This is without a doubt or else such ovens would have gone totally out of the market which has not happened, incidentally.

One of the main advantages of the Toaster Oven is that it is absolutely wonderful when it comes to making breads of various kinds. If you are a person who loves to make bread at home, it goes without saying that an oven would do much better for you than even the much touted and widely celebrated microwave oven. This is for the simple reason that the toaster type of oven is inimitably suited for making bread, which always comes out the best in such kinds of oven.

The reason why the Toaster Oven is able to do such a good job is because of the advantage of the convection mode of cooking. This is a mode that is able to take the heat from the coils of the oven and then spread it even all across the over. This is how the heating takes place evenly and totally uniformly inside such an oven. While some microwaves do have convection cooking, the effect is never as great as it is in the case of an oven that works on the toaster model. This is great from baking bread, making cakes and also roasting chicken.

Advantages of a Convection Microwave Oven

As you could probably tell by its name, a microwave convection oven, combines all the benefits of a microwave and a convection oven in one appliance! Its microwave radiation will heat up the water found the within your food while its heating elements and specially designed fan, will keep the hot air inside the oven circulating in order to make sure that your food will be uniformly cooked and perfectly browned!

It’s very common for foods heated using a microwave oven come out all soggy or steamed and some times, they may even lose their crispiness and become softer! Using a microwave convection oven, your food will always be cooked perfectly because of the perfect combination of the microwave radiation and the hot air circulating inside the oven!

The microwaves will cook your food from the inside while the hot air will take of making it brown and crispy! These amazing new appliances allow you perfectly cook everything, from chocolate chip cookies to a Thanksgiving turkey, provided you have a large enough oven of course!
