for the dot point refering to einstein adn his contribution to quantum phys, did anyobdy else get a graph/model of some exp that einstein did to prove qunatum stuff where u got a graph and something about stopping voltage and crap like that? bcoz tha syllubus doesn't say anything bout needing to know a graph/model to answer this dot point but i got a question in my half yearlies to discuss einstein's contributions to quantum and u had to answer that question using that weird graph... so my question basically is that if they asked it in tha half yearlies but not directly in the syllubus then cud they ask a question like that in the HSC exam where u have to use that graph to aid ur response on einsteina nd his contributions?
