In Figure 3.11 in the textbook (“Multiple Blackbody Curves”), an object at 1000 emits mostly?

A) infrared light.

I suppose you mean “an object with a temperature of 1000 K emits mostly”?

In that case the answer is A) infrared light.

Take lava coming out of a volcano, puts out peak radiation at about 3,000 nm. It emits far more energy in the infrared, which is none other than heat, than in the visible band, which ends about 750 nm.

E) none of the above
