D-layer

9.5
The lowest part of the upper atmosphere high above the Earth that reflects low radio waves
  • noun
  • Specialized
translation icon : capa D
  • Scientists monitor fluctuations in the D-layer to predict changes in radio communication quality.

Examples

  • The D-layer is critical for radio transmissions as it reflects waves back to Earth during the day.

  • The thickness of the D-layer varies depending on solar activity and time of day.

  • During the day, the D-layer absorbs low-frequency radio waves, reducing their transmission range.

  • The D-layer plays a crucial role in radio communication.

  • Can you explain how the D-layer affects radio signals?

  • During the day, the D-layer reflects low-frequency radio waves, which can affect long-distance communication.

  • Scientists analyze the D-layer to understand its impact on radio signal quality.

Morphology

D-layer = layer (transparent) = D + layer

Formed by adding the letter label 'D' to the noun 'layer'; the meaning is a layer named 'D', which is a literal and directly recoverable composition.

Etymology

The word D-layer names the lowest part of the ionosphere, the upper layer of air that affects radio signals. A helpful way to remember it is to think of the D as like 'day' because this layer appears in daylight and 'absorbs' low radio waves, so the D-layer weakens low-frequency signals and shortens their range.
