Cell phones are radio receivers and transmitters that use electromagnetic energy to send and receive information. Energy travels in waves. The distance from one wave to the next is the wavelength. Frequency is the amount of times the wave oscillates up and down per second. The higher the frequency, the more energy. Frequency is measured in Hertz. One Hz is one wavelength per second. Different electronical things are operated at different rates of hertz. At this point, the fastest connection runs at a 2.1 GHz (gigahertz) range-- that’s 2.1 billion wavelengths per second. Cell phones use low radiation called radio frequency (RF). A cell phone sends and receives
