Photoelectric Effect

I’ve taken some video clips (well Miss Horn did) of us trying out the Photoelectric effect as some people might never have seen it. I’m impressed how well it works, thanks to Mr Physics- who cleaned up the zinc plate. It needs polishing every 15 mins or so as it tarnishes very quickly and then wont work. The video of charging it positively and observing no drop in the gold leaf was just too boring to post. Hope you can watch them: I’ll have to try Plan B if not.
