4. When electromagnetic radiation (light) is produced it usually takes two steps. One will be an endogonic step (endogonic=endothermic) and another will be an exogonic (exogonic=exothermic). These steps are
what you described in both interpretations #1 and #2 above. You are to clearly describe which
step is the endogonic and which is the exogonic. Provide a brief explanation to back up your response.
