Figure 4-2 in the text 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 the object
A) is not visible but might be detected with equipment sensitive to nonvisible radiation.
B) emits no radiation, like all blackbodies.
C) emits visible radiation but not as intensely as at longer wavelengths.
D) emits no visible radiation but would emit visible radiation if its temperature were increased.
