How does an LED light change when dipped in liquid nitrogen? 💡 Museum Educator Adelaide plunges an LED into liquid nitrogen and watches its color shift from orange to yellow to green. Temperature affects the LED’s “band gap,” the amount of energy electrons need to jump across the material and create light. As the LED cools, the energy gap increases, and the light shifts to higher-energy colors. When it warms back up, it turns to orange again. #Chemistry #ScienceExperiment #Light #LiquidNitrogen

Do you use LED lights? I’ve spent the last three weeks testing over thirty different models and reading dozens of research papers about all the different ways these things can impact our health, especially in the context of headaches and migraines. I have gone so much deeper than I ever intended to. But soon I’m going to be releasing multiple videos here, as well as a really cool interactive dashboard I’ve been building for you guys to look at all my testing results. Probably a longer YouTube vi
