These objects may be described as perfect Lambertians, and one law about these objects predicts the ultraviolet catastrophe. Another law concerning these entities explains the utility of infrared sensors because it predicts that an object's temperature is two point nine millimeters Kelvin divided by the wavelength at which it radiates the most, which can be modeled by a curve named for Planck. Besides the Rayleigh-Jeans law and Wien's law, a better-known equation predicts that the radiant flux of is proportional to the fourth power of its temperature. For 10 points, identify these objects that absorb all incident light.
