Web14 apr. 2024 · The ionosphere is a region of the upper atmosphere that extends from about 70 to 500 km in altitude. It is a region where some of the atoms have had their outer electrons removed by extreme ultra-violet (EUV) and X-ray radiation coming from the Sun. The atmosphere is thus said to be partially ionised - hence the name, ionosphere. Web5 sep. 2024 · Hi all, I am trying to understand about collision frequency that happened in ionosphere layer.
