Sunspots and Radio Reception
Name: Sabrina M.
How does sunspot activity affect radio reception?
The sun emits light waves of all frequencies, even as low as radio waves and
as high as gamma rays. Our eyes only see the visible light, but it is all
there. The sun also emits many charged particles. When sunspot activity
increases, solar flares result. These are extra bursts of x-rays and
electrically charged particles. When this extra activity reaches the earth,
it interferes with all electromagnetic waves. It is most noticeable in the
low frequency radio waves.
