You’re Glowing!
You just can’t see it. Our eyes are designed to detect visible light. Anything that radiates heat also radiates infrared light. (The reason for this is based on quantum chemistry.) So we’re glowing in a color we can’t see all the time, as are all the things around us! But, do you know what can see Infrared Radiation (IR)? A thermal camera! How does it work? Use the thermal camera to explore your surroundings. Thermal cameras are used every day to see things we can’t see with our eyes. Firefighters can find victims through smoke, animal lovers can see critters in the dark, electricians can find bad wiring through walls, all using the power of IR detection!
