Figure 5-12 in Universe, 11th ed., shows that a blackbody with a temperature of 3000 K emits radiation that peaks at a wavelength much longer than wavelengths in the visible part of the spectrum. This means that:

A)the object is not visible but might be detected with equipment sensitive to nonvisible radiation.
B)the object, like all blackbodies, emits no radiation.
C)the object emits visible radiation, but not as intensely as at longer wavelengths.
D)no visible radiation is emitted, but visible radiation would be emitted if the temperature of the object were increased.
