Earth emission spectrum
WebEarth's surface emits the absorbed radiation, approximating the behavior of a black body at 300 K with spectral peak at f max. At these lower frequencies, the atmosphere is largely opaque and radiation from … WebThe spectrum of a blackbody is continuous (it gives off some light at all wavelengths), and it has a peak at a specific wavelength. The peak of the blackbody curve in a spectrum moves to shorter wavelengths for hotter objects. If you think in terms of visible light, the hotter the blackbody, the bluer the wavelength of its peak emission.
