# Why does the lines represent in Feynman diagram? watch

1. Apparently it doesn't represent the path of the particles which was what I assumed.

which line?

the straight ones are just the "direction" in which the particles are moving
i.e. on that diagram imagine as time goes on the particles move up

the squiggly line just represents an interaction with the particles

Oh right, OK thanks

4. Figure 3^^

Sorry, I'm just confused a little. In my textbook it says "In figure 3 the W boson In each case meets a neutrino or Antineutrino changing them into a B- or B+ particle".

It just looks as if the W boson is being transferred (as it's the squiggly wave). It isn't really meeting anything? Can someone explain tha diagram to me please ?
5. Moved to Physics.
6. The arrows represent the progression in time and the wiggly line represents the bosons (interaction particle) interaction between particles.

the boson is emitted from one particle and absorbed by the other
