Does anyone know how close a photon needs to be to a nucleus (an ion really, no shielding from electrons) for pp to occur? I assume it's a probability as a function of distance, any ideas/equations?
I don't see where there will be constructive interference. At the mirror surface I certainly can't see it, apart from the magnetic fields as they are at an angle to each other and as you make the angle closer to 0 they cancel. however along the beam I can see the electric fields cancelled and...
Take two lasers of the same intensity and wavelength and aim them at 30 degrees at the same spot on a mirror, so that at the surface the waves cancel perfectly.
What happens? How can the wave be reflected if there is no field present?
Does this mean that the tunnelling time was actually zero, and the electron 'skips' over the gap, or does it mean that the electron wave travelled at the speed of light followed by an instantaneous jump later on
Does anybody know what happens when say a laser accelerates charged particles?
Do photons get absorbed and the intensity of the laser drops, or do they get absorbed and scattered and there's a redshift of the photon etc
As far as I know, individual photons do diffract. However the question was not do they diffract, but how does the wave cope with running into say, a free electron. It's electric field would accelerate the electron but that would take energy. So obviously the photon isn't sub divided. I can't see...
In the single slit experiment, individual photons may be diffracted. The electric field of the em wave should accelerate charged particles in the screen (if it were a capacitor for example) but only one packet of energy exists. The photon may be absorbed after many wavelengths of light have...
