Which mechanism causes signal distortion during radio wave propagation through a forest canopy?

💡 Explanation

When radio waves propagate through a forest, multi-path interference occurs because waves reflect off numerous leaves/branches creating multiple paths, leading to Rayleigh fading which distorts the signal. Therefore Rayleigh fading is the correct consequence, rather than diffraction, attenuation or Doppler shift which require different propagation environments.
