Can someone explain to me what this is? All we were told in my Physics of Stars module was that for a plasma,(adsbygoogle = window.adsbygoogle || []).push({});

[tex]L \gg \lambda_{D}[/tex], where [tex]\lambda_{D}[/tex] is the Debye length.

We were also told that it's an "e-folding distance" for a potential, but that doesn't help to understand it.

I'm not even sure what L is either (the length of the plasma?? ) :/.

Thanks.
