What is implied by the term 'black body' in the context of outgoing energy?
Understand the Problem
The question is asking about the concept of 'black body' in physics, specifically relating to its properties concerning outgoing energy. It is asking to identify which statement accurately defines this term.
Answer
A black body is an idealized object that absorbs all incident electromagnetic radiation and re-emits energy based on its temperature.
In the context of outgoing energy, a 'black body' implies an idealized physical object that absorbs all incident electromagnetic radiation without reflecting any, and re-emits energy across a spectrum dependent on its temperature.
