Question

Quizplus · Accepted Answer

Synchrotron radiation is produced when high-energy electrons spiral through a magnetic field. Therefore, the fact that the radio lobes radiate synchrotron radiation indicates that high-speed electrons are spiraling through a magnetic field. The other choices are not directly related to synchrotron radiation.
