How Microwave Ovens Work, and Why Use One?
A look at the origin of microwave ovens. Many kitchens now have a microwave oven fitted, and they have reduced cooking times dramatically. What are microwaves? In frequency (rate of vibration) and wavelength, microwaves fall in the electromagnetic spectrum between infrared rays and radio waves. Microwaves are nonionizing energy. They are much less powerful in effect and do not have sufficient energy to dislodge electrons from atoms, which is why man has felt relatively free to utilize this form of energy for its beneficial advantages. To ensure certain safety standards, the Food and Drug Administration (FDA) has the responsibility for carrying out an electronic product radiation control program mandated by the Electronic Product Radiation Control provisions of the Food Drug and Cosmetic Act. What They Are Used For About 80 years ago there were no man-generated microwaves. Only small amounts of microwave radiation from the sun and other sources in earth’s galaxy found their way into our
