Which mechanism limits radio signal propagation through dense forests?

💡 Explanation

Vegetation diffracts radio waves due to varying refractive indices; the mechanism being vegetation-induced diffraction. This distorts and weakens signals because radio waves bend around obstacles, therefore limiting propagation, rather than being merely absorbed or rotated by the forest canopy.
