Yesterday I read that we can affect the path and the 'form' (particle or wave) of a photon after the fact (Wheeler's delayed choice experiment). Part of what is puzzling me is the beam-splitter. Are the individual photons actually being split into two new photons of lesser energy?

This questionquestion implies that you cannot split a photon but it seems that beam splitters do exactly that.

What happens when a photon hits a beamsplitter?
