Use Figure 7.6 to estimate the relative amounts of infrared radiation emitted by blackbodies of 7500 K, 6000 K, and 4500 K.

FIGURE 7.6 The Spectra of Radiation Emitted by Blackbodies with Temperatures of 4500 K, 6000 K, and 7500 K A hotter blackbody is brighter than a cool one at every wavelength. The visible part of the spectrum (divided here into its constituent colors) is bordered at short wavelengths by the ultraviolet and at long wavelengths by the infrared.
