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.

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

Explanation:

In order to study the light emitted by the hot bodies, a model was proposed in which the idea was to perform the calculations only of the radiation produced by the thermal agitation of the body. Such a body should absorb all the radiation that came to it and could not reflect it. Thus, the body would have to be totally black, hence the name of the model: blackbody radiation.

First, we have to really understand what blackbody radiation is. When we warm a body, it emits electromagnetic radiation. Thus we can say that the spectrum of this radiation depends on the body temperature. For example, the furnace of a steel industry or the sun produces radiation through thermal agitation. If we look at the red coal, we actually see the blackbody radiation of a body at very high temperature.

From this context, it was stated that as energy is added to an object that acts as a blackbody radiator, its emissions move to the ultraviolet part of the electromagnetic spectrum.
