An electron makes a transition from a higher energy state to a lower one without any external provocation. As a result of the transition, a photon is emitted and moves in a random direction. What is the name of this emission process?
A)stationary emission
B)stimulated emission
C)spectral emission
D)spontaneous emission
E)specular emission

Question

Quizplus · Accepted Answer

This emission process is called spontaneous emission, as it occurs without any external stimulation or provocation. Option A (stationary emission) and option C (spectral emission) do not accurately describe this process. Option B (stimulated emission) involves external stimulation, which is not present in this scenario. Option E (specular emission) refers to a different phenomenon related to reflection.
