im so confused about this so id really appreciate it if someone can help me
okay so i get the general idea of it - electromagnetic radiation of a certain frequency has to be shone on the metal (usually uv light), and photons interact with the metal releasing electrons.
i get all that stuff
but how does this give evidence for the particulate nature of light?
like why cant a wave do this?
and also i get about the wave-particle duality, that particles exhibit wave like properties and vice versa. but if the photoelectric effect is evidence that light is a particle, then how can E=hf where f is the frequency? cause frequency is concerned with waves. so if thats the case then surely it gives evidence that light is a wave!? :S
someone please tell meeeeee
