## Main Question or Discussion Point

Hi,

I'm sorry if this question has already been answered somewhere and I'm just too incompetent to find it, buuut:

As the title already says, I really do not get that part of quantum physics (if you can even say I'm getting ANY part at all...).

As I searched all Google for an answer I just found out about Schrödinger's equation which uses the De-Broglie wavelength, which is

I understand that, first, every quantum particle has a wavefunction and second, the probability of finding a photon at place x is proportional to the lightwave's intensity. But, which would at least seem logical, calling the lightwave the photon's wave function doesn't seem to be correct, according to Google :D

So what am I not getting? Do photons even have a wavefunction determining their probability of presence?

The only kind of promising-looking stuff I found was Maxwell's equations, something about Dirac and some Klein-Gordon equation.

I also tried asking my teacher but we kind of always end up confusing each other...

Any help is very appreciated, thank you

Oh and please excuse any language mistakes, I'm not a native speaker

*the analogy*of the wavelength of light for matter particles. So this means Schrödinger's equation can't be used for photons, can it?I understand that, first, every quantum particle has a wavefunction and second, the probability of finding a photon at place x is proportional to the lightwave's intensity.
