Layers of the ionosphere
WebF1 Layer is a sublayer of the F layer This layer is located above the E layer and will have the highest density up to 220 kilometres. It behaves like the E region, which follows Chapman’s law. The critical frequency of this layer spans from 5 MHz to 7 MHz, depending on the application (noon time). 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.
