Make detailed notes on the following;
The photoelectric effect - what is the work function and threshold frequency?
How did Einstein explain this effect and how did this lead to the photon theory of light?
How can you calculate the maximum kinetic energy of the emitted electrons?
Electron diffraction - what does this give us evidence for?
What is de Broglie's equation and what does it mean?
Young's double slit experiment - what is it and what did this show?
What is the significance of this experiment?
Also try questions 1,2 and 4 from the unit 5D Turning Points June 2010 paper available on the AQA website
