A'Level Physics 9702 (Stopping Potential)
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.
