## Electromagnetic waves are classified using what measurement

Electromagnetic waves are waves that contain an electric field (E) and a magnetic field (M) and carry energy. It has classified radio frequency electromagnetic radiation as Group 2B - possibly carcinogenic. The e. Wave motion is the transport of energy from one point in space to another without the transport of matter. and Serhir, M. were used as the measurement set. EM radiation types are characterized and classified by their specific wavelengths, but this has nothing to do with brain waves. Chauraya, J. Since RF waves have both electric and magnetic components, the electric field strength is measured in volts per meter (v/m) and the mag- netic field is measured in amperes per meter (A/m). Resulting from the technological innovations, the use of electromagnetic fields gradually increases and thus people are exposed to electromagnetic waves at levels much higher than those present in the nature (1,2,5). SEBAALY A new technique was developed to measure the moisture content in hot-mix asphalt concrete. Electromagnetic fields have their own alignment, called polarization, that scientists can measure. Each of these frequencies has its own properties and characteris-tics which make it distinguished from others.
