Quizplus · Accepted Answer

Black holes emit high-energy X-ray radiation, so an X-ray telescope in space would be the best choice for studying them. Gamma-ray telescopes could also be used, but they are more suited for studying events such as supernovas and gamma-ray bursts, which can occur near black holes but are not directly related to the black holes themselves. Infrared and radio telescopes would not be effective for studying black holes, as they do not emit significant amounts of radiation at those wavelengths.
