Which of the following best describes the ultraviolet catastrophe of blackbody radiation?

A. As energy is added to an object acting as a blackbody radiator, its emissions move to the ultraviolet part of the electromagnetic spectrum.

B. As energy is added to an object acting as a blackbody radiator, its emissions remain in the visible part of the electromagnetic spectrum.

C. As energy is added to an object acting as a blackbody radiator, its emissions become radioactive and dangerous to humans.

D. As energy is added to an object acting as a blackbody radiator, it ceases to emit any radiation and the added energy ignites the object.

The ultraviolet ctastrophe in general refers to the fact that a blackbody emits an infinite amount of energy when in balance due to some errors in calculations in the early years of quantum physics. Thus, as energy is added, its emissions go to infinity in the ultraviolet spectrum and it releases infinite energy. This was solved later by Planck. The correct answer is A;
