Question

Two objects of the same size are both perfect blackbodies. One has a temperature of 3000 K, so its frequency of maximum emission is in the infrared region of the spectrum. The other has a temperature of 12,000 K, so its frequency of maximum emission is in the ultraviolet region of the spectrum.

Compared to the object at 3000 K, the object at 12,000 K:

A. emits more light in the infrared region of the spectrum.

B. emits more light in the visible region of the spectrum.

C. emits more light in the ultraviolet region of the spectrum

D. emits more light in only two of the three listed spectral regions.

E. emits more light in all three spectral regions.
