Why isn't radio wave reflection in the ionosphere direct?

AI Thread Summary
Radio wave reflection in the ionosphere is not direct due to the complex interactions between the waves and the charged particles in the upper atmosphere. The ionosphere acts as a refractive medium, causing waves to bend rather than reflect directly. This phenomenon is crucial for understanding how radio waves, particularly high-frequency (HF) signals, propagate and are affected by solar activity. The discussion highlights the need for clearer questions to facilitate better responses. Understanding these principles is essential for those interested in radio communications and atmospheric science.

Hi,
why the reflection in ionosphere isn't direct?,
 
Engineering news on Phys.org
Please elaborate. Reflection of what? Radio waves?

This topic seems more appropriate for physics or astrophysics forums.
 
A little helpful advice for you Karim. Many of your posts are like this. We can't read your mind and without any more information than you have given we will not be able to help you. Please give a little more information in the future when posting. Incidentally, looking at your post history you appear to have a very broad range of interests. Where are you from?
 
just a guess NDTM

IF I may interject I think his question is concerned about how the upper atmosphere protects this planets from the sun.
 
Sorry I mean Radio wave like HF frequency.
