WebElectromagnetic radiation can be described by its amplitude (brightness), wavelength, frequency, and period. By the equation E=h\nu E = hν, we have seen how the frequency of a light wave is proportional to its energy. WebAs the radio waves are turned off, the atoms return to their original position and send back radio signals. These signals are received by a computer and converted into an image of the part of the body being examined. This image appears on a viewing monitor.
