Micro Vacuum
What causes thunder? I know ... lightning. I am not a dork. But what the physical properties that cause?
In class electronics instructor assumed that the massive amount of electricity actually burned the air molecules he used as a conductor and has created a vacuum. The air rushing back into space causing the crackling. This should be true in both micro-and macro-events. (Tesla coils, etc.) Anyone?
Absolutely correct! What's "burned" (oxidized) here is mainly due to oxygen in the air - the (fast) oxidizing causes a vacuum which causes the air in this process to move quickly, and when these air masses "collide", they swing ... and what we hear is "thunder". This basic principle works in all conditions, Sometimes when you have a short circuit in a switch, for example, you will see a rather bright flash followed immediately by a kind of "bang". This is which also produces at least a portion of sound in an internal combustion engine, but because of the pressure generated by the piston, there is not really too much empty.
