those were real nice websites but i need summarised notes on the particle wave theory cause i didnt get the question in the jan 2010 paper U2 physics  based of the particle wave theory :(

just learn that table given in the notes..that differentiates particle theory with the wave theory, BIB  :P :P

well since tomorrow, im getting the whole story behind de broglie and his experiment, wat i require is that for example, in the particle theory, one photon interacts with one electron on a metal surface to release one photo electron where as the wave theory states that the more the intensity of the light falling on the metal surface, more the energy is build up in the electron.

i wanted stuff like this, my teacher gave these notes but i don't hav um cause i was sick or soemthing so couldnt make it to school, all the links were extremely helpful, thank u all :) but wat i require are the comparison notes :)

A wave model would predict that weak radiation would eventually release large numbers of electrons but this is not what happens.
Considering light as photons means that weak radiation can cause instantaneous release of some electrons if the frequency is greater than the threshold frequency. Hence one photon is responsible for the release of one photo-electron.
