Can Electrons Pass Through Fiber Optic Cables Like Light Waves?

AI Thread Summary
Electrons cannot pass through fiber optic cables like light waves due to their interactions with atoms in the cable. While electrons exhibit wave-like behavior in experiments such as the double slit, their high-speed acceleration does not enable them to travel through fiber optics as light does. Unlike electromagnetic waves, electrons are fundamentally different entities that cannot propagate through the medium without being stopped. The unique properties of light allow it to transmit through fiber optics, whereas electrons quickly lose energy and are absorbed. Therefore, fiber optic technology is specifically designed for light transmission, not for electrons.

If electron can show behaviour of wave in double slit experiment like interference, diffraction, can it pass through fibre optic cables, if it is accelerated with high speed into the cable?

If you're thinking of shooting an electron down the cable like you do with light, no. The electron would quickly interact with the atoms in the cable and be stopped. Note that an EM wave is a very different 'entity' than an electron.

This is from Griffiths' Electrodynamics, 3rd edition, page 352. I am trying to calculate the divergence of the Maxwell stress tensor. The tensor is given as ##T_{ij} =\epsilon_0 (E_iE_j-\frac 1 2 \delta_{ij} E^2)+\frac 1 {\mu_0}(B_iB_j-\frac 1 2 \delta_{ij} B^2)##. To make things easier, I just want to focus on the part with the electrical field, i.e. I want to find the divergence of ##E_{ij}=E_iE_j-\frac 1 2 \delta_{ij}E^2##. In matrix form, this tensor should look like this...
Thread 'Applying the Gauss (1835) formula for force between 2 parallel DC currents'
Please can anyone either:- (1) point me to a derivation of the perpendicular force (Fy) between two very long parallel wires carrying steady currents utilising the formula of Gauss for the force F along the line r between 2 charges? Or alternatively (2) point out where I have gone wrong in my method? I am having problems with calculating the direction and magnitude of the force as expected from modern (Biot-Savart-Maxwell-Lorentz) formula. Here is my method and results so far:- This...
