The minimum energy required to eject an electron from the surface is called the photoelectric work function.To be precise to eject means force or throw (something) out
So energy equal to work function would surely eject an electron from metal surface
but according to the video below
At time 56:37 to 56:44 ,57:23-57:30 and at time 35 :26
it seems if metal is provided with energy equal to work function electrons would not come out from metal surface rather they will vibrate and come back to their positions.I think electrons should stand still just outside the metal surface when energy equal to work function is given?
Is it right?
