To determine the meaning of characterizing a nebula as diffuse, we can break down the options provided and select the most appropriate answer.
Option 1: "Its edges do not have clear boundaries." - This implies that a diffuse nebula does not have well-defined or distinct edges.
Option 2: "It reflects only visible radiation." - This statement refers to the reflective properties of the nebula rather than its diffuse nature.
Option 3: "Its edges have clear boundaries." - This contradicts the definition of a diffuse nebula, as it is characterized by having fuzzy or indistinct boundaries.
Option 4: "It reflects only non-visible radiation." - Like option 2, this statement refers to the reflective properties of the nebula, rather than its diffuse nature.
Considering the explanations above, the correct answer is: "Its edges do not have clear boundaries."
