My Ideas

Since light is a wave we should conclude that the photon that leaves an object is not the same photon that arrives.  We only know that if one photon leaves then only one photon can arrive.   So there is a chain reaction in which there is a path but it's not necessarily a straight one.    There is a single path though of one to one interactions.    What if a wave consisting of a single photon is actually a chain reaction where a photon interacts with an electron which then interacts with an electron.   The distance between each interaction is the wavelength.  The number of interactions is the frequency.     This makes me wonder though how it would be possible for the interactions to be so perfectly periodic.    Who knows if a photon will encounter an electron at a particular point.  If you substitute the electron for another type of particle say a electric photon.  As if there were a photon for the electric field and a photon for the magnetic field then it would be easier to underst

There seems to be an almost mathematical property of light.   Where light can be in two states.  Either it's a ray or it's being diffused.  It's almost always forming rays though even when diffused.  However you could say that diffusion is about destroying a ray.  A ray carries information about it's origin in the wave-fronts which comprise it.   If it passes through glass it's giving incorrect information about it's origin because the rays have been altered by being offset.   This itself is the result of diffusion.  Light diffuses around the atoms in a glass (because the wavelength is larger than the distance between atoms)  There seems to be something about light that makes it hard to diffuse. Diffusion takes place when light passes through a slit smaller than it's wavelength.  This is true of all waves.  A ray is a series of wave-fronts stacked up to form a ray.  An analogy would be a building.  Imagine a tall skyscraper as a ray pointing straight up.
