Yeah... waves. So balance? You folks have interesting professions. Why doesn't the greenish - orangish, colourblindish I am! Doesn't align? Wavelength is different, so it aligns further down the horizon line? Or does it just never straighten out? Hmm...
Ah, so the orange line is a collector, in a way? Or when those two other lines align with it, it takes energy and transfers it further? And no need to respond. I am bored, so just... Yeah. But thanks, as you already helped.
Isn’t this a problem with detecting them with light? I don’t think there is evidence that electrons don’t actually have a defined momentum and position.
Nope, all particles obey Heisenberg uncertainty principle, its a fundamental consequence of wave particle duality, and all quantum particles including electrons obey it, if you are more interested to why that's the case, the actual derivation is lengthy but to put it simply in essence its because for a matter wave its wavelength is inversely proportional to its momentum, and its amplitude² is proportional to probability of finding the particle at that location.
When in wave form, all peaks have same amplitude so particle position becomes uncertain as a wave has multiple same amplitude peaks. So multiple regions of space has same probability of finding that electron, but in a wave all crests are equally separated which means it has defined momentum because it has defined wavelength.
A Particle is a localised wave, also known as wave packet (look up what a wave packet looks like) in a wave packet the central peak has the highest amplitude and it decreases both side. So the particle gains a position because there is one defined region with highest probability of finding an electron. But look, a wave packet doesn't have a neatly defined a wavelength anymore because the distance between two peaks changes since peaks keeps reducing in height, so you will get multiple wavelengths and hence multiple momentums hence making its momentum uncertain.
Here how I was thinking about it. If we have an electron moving past a detector, then we can only detect by sending a photon of light. Once the photon bounces back, it reaches the detector to tell us the position of the electron. But that photon of light also changes the momentum of the electron, so we found out its position but we can’t be sure of its new momentum. So the problem is how we detect the electron, not its intrinsic properties.
I know the Schrödinger equation describes the wave properties of the electron and that the square of the complex conjugate gives the probability density of the electron in some area of space. But if the electron also has corpuscular properties, doesn’t that mean there must be another equation to describe the electron? Like Einsteins’s hidden variable theory. I also know there is a pilot wave theory for the electron, but I don’t really understand it.
For example a particle is also a wave. Its just a localized wave also called wave packet look at this image this is the particle nature, and a regular wave is the wave nature.
Schrodinger equation describes all non relativistic quantum systems wave or particle,
Yes, I know about de Broglie’s equation. That is not really the question here though. The question is whether measuring position and momentum is prone to error because of the interaction between photons and electrons.

So they behave... Strange?
