💡 Listening to Matter When It Learns to Glow: How an Incandescent Light Bulb Works
From section: 🌈 Warm light, color, and the feel of incandescenceThis relationship becomes especially noticeable when an incandescent bulb is dimmed. Reducing the electrical power lowers the filament’s temperature, decreasing its brightness while shifting more of its radiation toward longer, redder wavelengths. The bulb therefore does not merely produce less light. …
