Ground wave vs. sky wave stability

[Titan97]

Homework Statement

Is sky wave signal less stable than ground wave signal?

Homework Equations

None

The Attempt at a Solution

Ground waves face attenuation because when it glides over the surface of earth, there will be induced fields which can oppose the wave.

In case of sky waves, it depends on the state of the ionosphere which varies day to day.

I don't know how to compare them.

What does "stable" mean in this context?

I am not sure. Maybe it means consistency or reliability. But which wave has lesser attenuation?

I am not sure. Maybe it means consistency or reliability.

how about listing some of the things you would expect to affect the propagation of a ground wave Vs a sky waveDave

 

[Titan97]

Induced EMF can affect ground waves.

The state of ionosphere will affect sky waves

 

[Simon Bridge]

It may be useful, then, to make a number of columns - one each for the things that "stability" could mean - then go through each of the things that could affect the EM waves in each approach to see how each affects the different forms of stability. i.e. how does "the state of the ionosphere" affect "consistency"?
Have you looked through your notes to make sure you have not had some statements about reliability as part of the coursework already?
The statements may be indirect. Usually something would not be asked unless it has come up in class in some way.

No comparison was done during class.

Never suggested that you did any ...
