Resurrecting Titanosaurus : The Black Fire
In middle-school, physics teachers would tell us the color of objects is the type of light that has been reflected, on the other hand, black things are ones that absorb all visible light and reflect "nothing".
Fire, is also no stranger for us, the burning of a material that releases heat and light.
Hence, how could the fire be black?
This picture shows the experimental phenomenon of a flame that looks black in the real world without any retouch. Instead, it was the orange light in the back ground playing the trick! The black fire is a flame of ethanol solution of NaCl.
Normally, electrons of the Na atom could jump up the energy level and fall back to original state under burning condition to release a bright yellow light. But under the orange-light environment--created by the sodium-vapor light that emits approximately monochromatic light of Na spectrum--the electrons could absorb the light with exact frequency and corresponding energy to return to its excited state.Thereby, this allows it to absorb all available light in this specific circumstance and reveal a dark color.Besides, I gave this picture the name of Resurrecting Titanosaurus because the shape of the fire in this scene looks very much like the Titanosaurus, a kind of dinosaur with long necks and dark color.
The black fire was basically collaborating the flame reaction with fundamental property of color, yet this amazing collaboration reveals how any simple thing in this world could still bring you surprise with further exploration!
