The ionosphere is the layer of the atmosphere that reflects radio waves. This effect is caused by the ionization, or electrical charging, of the gas particles present in the upper atmosphere by X-rays and ultraviolet rays emitted by the sun.
The ionosphere is defined as the layer of the Earth's atmosphere that is ionized by solar and cosmic radiation. Short wave radiation that penetrates the Earth's atmosphere does not reach the surface.A few examples of short wave radiation are x-rays, ultraviolet and gamma rays. When these waves pass through the atmosphere, they ionize molecules of oxygen and nitrogen and create a thin ionized region known as the ionosphere.he ionosphere is very important because it can be used to help transmit radio waves across the globe. The radio waves are able to bounce off the ionosphere for communication purposes.
