A Nature of radiation emanating from a body v/s frequency

  1. Jul 7, 2016 #1
    Does the nature of radiation emitted by dense bodies like black holes differ in frequency from radiation emitted by regular stars like our Sun ? I believe that the former radiates more x-rays and high frequencies rather than the latter which radiates mainly uv, visible and infra-red ranges. Is this so ?

    Black holes do not radiate in the way you seem to think. Deducing the frequency of Hawking Radiation apparently is quite complex.

    Phinds is correct
    ..... maybe you were thinking of the X-rays that are radiated by the material falling towards the black hole, prior to it crossing the event horizon
    do some googling on Cygnus X-1 for one of the earlier black hole X-ray sources identified
