Eletromagnetic radiation with a frequency below the ionosphere's plasma frequency will generally be reflected. The specific frequency depends on the density of ionospheric plasma which can vary at different altitudes, but also different geomagnetic latitudes and from day to night. For a typical daytime mid-latitude ionosphere, the most dense part of the ionosphere, (the "F" region), will reflect radio frequencies up to ~2.8Mhz (assuming an electron density of 1e11 m-3).
ionosphere
the ionosphere is important is the it is in the thermosphere
The ionosphere gets its name from it being charged with ions. It is called the ionosphere because it is in the shape of a sphere.

these ionised particles,reflect the radio wave to earth back.depending on the density of the ionosphere,at the time determins the amound of radio waves.this will affect clear reception.the height of the ionosphere involves reflecting angle,which gives long length hops.in this way long distance communications are affect by ionosphere.

The Ionosphere
The Ionosphere.
The thermosphere contains the ionosphere. The ionosphere is the layer that is ionized by the solor radiation.
