Web13 apr. 2024 · Statement 3 is correct: There are two important layers in the ionosphere viz. E layer or Kennelly Heaviside layer that reflects the medium radio waves, thus helping in short distance radio communication and F layer or Appleton layer that reflects the short radio waves and helps in long distance radio communication. WebAn introduction to the role of ionospheric-layer tilts in long-range HF and VHF radio propagation is given. Tilts in the reflecting layers can have a first-order effect on radio propagation as a consequence of the curvilinear geometry of the earth. Low-angle rays reflected from a properly oriented, sufficiently tilted F layer will propagate beyond the …
