The relation of the E layer to radio waves is based mainly on which feature?
Answer and explanation
Correct answer: Ionized particles affecting the path of waves
The E layer is an ionized region of the ionosphere. Free electrons and ions can change how radio waves are refracted, absorbed, or reflected, especially for suitable frequencies and propagation conditions. Therefore, option B gives the relevant physical mechanism. Rainfall, seawater condensation, and surface dust are lower-atmosphere or surface processes and do not explain the E layer’s radio connection.
