Microwave Ovens :: essays research papers

Microwaves are low on the electromagnetic spectrum. The electromagnetic spectrum is a range of all the possible electric radiation. relative frequence of a wave is the number of waves per second and the frequency of a atom-bomb is between 300 MHz and 300 GHz. The wavelength of a wave is the aloofness from one peak of a wave to the peak of a future(a) wave and a wavelength of a microwave varies from one millimeter to 30 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 intimately microwaves until he predicted equations that would prove the existence of microwaves. In 1888, Heinrich Hertz took these equations and employ them in an experiment. He made an apparatus that produced waves and detected these waves. The experiment displayed the different wavelengths of sure waves, such as the short w avelength of microwaves. The discovery of microwaves permitted it to be used for commercial message purposes.Microwave ovens are the best example of a commercial physical exertion of microwaves. Microwave ovens use microwaves at a frequency of 2450 MHz. The Microwaves travel and baffle the water, fat, and sugars to vibrate resulting in the foods temperature rising. This type of energy is called nonconductor energy. This benefits the food making process and bothone who buys TV dinners. Another instance of microwaves is carrell phones. Cell phones use an antenna and a little transmitter to link 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 overseas telegram TV and the Internet, use microwaves to transmit the signal in order to broadcast. These twain sources that use microwaves permit faster communication between all areas of the world. These two sources that use microwaves are the around popular ways of entertainment for most of the United States. The commercial industry benefits from these products that use microwaves.Current studies prove undecided about the effects of microwaves. Microwave ovens can take in 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 match feet away according to Dr.
