What causes the color change when things start glowing because they are so hot?
In: 15
Black body radiation. Everything that has heat emits electromagnetic waves (light). Most things on earth don’t emit light in the visible spectrum but they do emit in the infrared spectrum (that’s why infrared cameras work for night vision). When you get something hotter it emits higher energy light entering into the visible light spectrum following the same pattern that we would see in a rainbow started with red then to yellow and so on as they all get mixed in we see white.
