Wasn't there a discussion back in the 20s or 30s regarding whether time actually existed? While the three dimensions exists through our senses, I think it was argued that time only existed because we had a memory. The human mind can remember the "past" and recognise it was different than the...
So that implies that a photon is a non localised entity. The double slit implies that the photon goes through both slits at the same time. Correct? Does this mean that a photon is non localised all the time or that it "magically" splits when it goes through the double slit and recombines after...
I might have a glimmer of hope here. So what's the "something"? I'm now wondering what the manfestation of the frequency we speak about. So now I've got two photons, one has a higher "frequency" and thus more energy, I trust that frequency does not mean vibration in the sense of a string. If...
Yeh, I've read QED, very good treatment, not enough math for me to really understand things. Odd that a problem that is so simple to demonstrate, and known about since Newton's time, has yet to be solved. Maybe it's Fermats last theorem for physicists?
So a followup question, in the double slit, since diffraction takes place, how does the photon know that the slit is there, considering it does not touch it?
Was recently re-reading QED and wondered whether there was any "simple" explination of partial reflection? How does the thickness of glass affect reflection if it's a particle?
A beginner question (at least not since my university physics course 20 years ago).
My understanding is thus:
light is made of photons
photons travel at speed c
energy of light is related to it's colour
So what's the difference between a blue photon and a red photon at a fundamental...
