A'Level Physics 9702 (Stopping Potential)

Tania Zahidi

Are students required to know stopping potential or the stopping potential graphs? I can't seem to find it anywhere specifically mentioned in the syllabus. In the syllabus it says you need to know that
hf = work function + K.E where K.E is 1/2 (mv^2) that's all. It doesn't mention K.E = eV or qV anywhere.


I was going to have a look for you but I am not sure which eam spec you are using as 9702 did not show up when i looked for it. Can you please tell me if it is AQA, OCR or Edexcel?
