Discussions

• Thanks to @JosBergervoet and @JanLalinsky for the answers, and also to @Ruffolo for the reference to another helpful question . I will present here the understanding I have gathered from these answers [stackexchange, 1 points]
• Yes. Yes, "black" referred to the visual appearance of something reflecting no visible light. Yes, historically. But Kirchhoff explicitly defined "completely black" technically as absorbing all inci [bsky, 0 points, 1 comments]
