Diathermy utilizes wavelengths from the EM spectrum that are highly regulated. What entity is responsible for the regulation of the “airwaves?”
The Federal Communications Comission
The amount of heat generated in deeper tissues will be directly proportional to the creation of eddy currents that have been induced perpendicular to the source of the EM energy. What is the term that is used to describe water-containing molecules, which influence whether or not they will rotate in response to the application of diathermy?
Diapoles
