An atom that emits light of a certain frequency is

Question

Quizplus · Accepted Answer

An atom that emits light of a certain frequency is likely to absorb light of the same frequency because the emission and absorption processes are the reverse of each other. This concept is the basis of many important technologies such as lasers and fluorescence spectroscopy. Choice A is incorrect because the fact that an atom can emit a certain frequency of light suggests that it has the capability to absorb that same frequency. Choice C is not necessarily true as fluorescence refers to the emission of light after excitation, not necessarily emission after absorption. Choice D is incorrect as there must be a correct answer.
