Radiofrequency will follow the path of least resistance, so if water is present, it will travel to the droplets of water, rather than to the plastic. What is Radio Frequency? Actual Definition: Radio Frequency is any frequency within the electromagnetic spectrum associated with radio wave propagation. (webopedia.com). In simple terms: Invisible waves of energy.
