    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

    The microwave oven, a tool that we use often in our busy lives to heat up foods when we just don't have the time or patience for a conventional oven to do its work. How does this device work? It's pretty simple if we use the basics of physics to explain it. Vibrations from the high frequency radio waves cause the water and fat cells in food to generate heat through friction of the molecules. An example of this using a turkey shows the molecules positive and negative particles acting through
