Abstract
We consider the various processes, in solar atmosphere, of the relativistic electrons ejected in association with flares and examine how these electrons will lose their energies.
In view of the above examination, we can show that these electrons will be trapped in the sunspot magnetic fields (∼100 gauss) and then lose the majority of their energies through the synchrotron radiation. So, the radio waves emitted by these synchrotron radiation processes will be observed as the type IV outbursts.
