High-energy radiation from a black hole. A continuous spectrum of light emitted from a hot solid object. None of the above. The electromagnetic spectrum is part of a refracting telescope. None of the above.
Blackbody radiation is the individual wavelengths of light emitted from blackholes.
None of the above. The blackbody spectrum is a continuous spectrum of light. The wavelength of maximum intensity decreases with increasing temperature. The total energy emitted increases with increasing temperature. All wavelengths are emitted with equal intensity.
