The electromagnetic frequency of a wave is defined as how many times the peak of this oscillation moves past a point each second. This has a major effect on the properties of the wave, including its energy.
There are a lot of people out there concerned about electromagnetic fields (EMF) and electromagnetic radiation (EMR or also known as radio frequency (RF)). People want to know how to measure EMF. So much so, that they purchase detectors and meters for themselves and attempt to study their own property and homes. It is great to take responsibility for your own concerns! However, there are likely many things that could be confusing your personal assessment.
