Target entity: Heaviside layer
Context triple: [Kennelly–Heaviside layer theory, relatesTo, Heaviside layer]
  • A. Kennelly–Heaviside layer theory
    Kennelly–Heaviside layer theory is an early 20th-century scientific model proposing the existence of a conductive layer in the upper atmosphere that reflects radio waves, helping to explain long-distance radio communication.
  • B. Hertzian waves
    Hertzian waves are early experimentally demonstrated electromagnetic waves that confirmed James Clerk Maxwell’s theory of electromagnetism and paved the way for modern radio communication.
  • C. Ekman layer
    The Ekman layer is the thin region of fluid near a boundary (such as the ocean surface or seafloor) where the balance between friction and the Coriolis effect causes the flow to spiral with depth.
  • D. Fresnel zones
    Fresnel zones are concentric regions on a wavefront used in wave optics to analyze and predict diffraction and interference effects, especially in near-field conditions.
  • E. Longuet-Higgins
    Longuet-Higgins is the surname of a notable British family that includes influential figures in theoretical chemistry, cognitive science, and mathematics.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
