D)mainly emission lines due to hydrogen

Question

Quizplus · Accepted Answer

The radiation produced by the radio lobes and jets from radio galaxies is mainly synchrotron radiation, which is emitted by highly energetic charged particles moving in strong magnetic fields. This type of radiation is commonly observed in the radio spectrum and is indicative of the presence of magnetic fields and high-energy particles in the vicinity of the radio galaxy or jet. 21-cm radiation, black body radiation, and emission lines due to hydrogen are not typically associated with radio lobes or jets.
