Answer:
Solar Flares and Prominences
Explanation:
The sun is source of light and heat energy and it supports life on earth because sun is the primary source of energy. But sun is also a star and is a glowing ball of hot gases mostly hydrogen and helium. There are so many activity that takes place on surface of sun. But the two activity solar flare and prominences affect the radio communication.
Solar Flare are electromagnetic energy built up in the sun atmosphere .These energy travel with the speed of light and affect outer atmosphere of earth. These increased level of X rays and ultraviolet rays ions the layer of ionosphere which becomes superionised. thus causing destructive interference.
The radio waves travel in ionosphere and frequently collide with electron lose energy and completely blackout.
Prominence is defined as gaseous cloud of calcium,hydrogen and other gases floating above sun chromosphere and emit violently particularly near sunspots sometimes travel through space and affect radio communication.
