If there is a large current, it heats up the air and If there is a large current, it heats up the air and makes light. Thus, the sparks, flames etc are direct makes light. Thus, the sparks, flames etc are direct evidence for the model of atoms!evidence for the model of atoms!

An electron shooting out of the tesla coil hits lots of atom and knocks one of their electrons to a higher energy state. When the electron falls back down, it emits energy in the form of a photon, which travels

to our eyes and we can see as light.
