Re: Microwave & Tesla coil
It is plasma.
Air is a mixture of gasses. When heated gasses conduct electricity it becomes plasma.
So microwaves have a travel distance which exceeds the arc distance off the corona of the Tesla coil.
What you described likely suggests that the microwaves and the high frequency electricity travel in tandem
It’s really crazy physics to try and wrap your mind around
And a very scary topic
I hate stuff that could be harmful
I only ponder inventions which will set humanity free
And how to make better toast
