Okay, let me prelude this by saying I only have an -EXTREMELY- limited understanding of classical physics, and zero knowledge of quantum mechanics. This is really just my asking a few questions in regards to an idea I had for an experiment, and what would be a good and accurate way to scientifically measure it. If this is something that requires an advanced degree in QFT, please feel free to ignore this post/move it to the trash bin. [PREMISE] So according to Maxwell, an oscillating electric charge set at a specific frequency generates EM/light waves. The strength of the induced field is proportional to the rate of change of the inducing field. Now the electric & magnetic fields 'regenerate' each other at a constant speed - the speed of light - so energy conservation is maintained. The frequency can change, but the speed of propagation never changes. [QUESTIONS] - 1 and 2 are not related to the experiment. 1: Can this process be reversed? Could you somehow translate an EM wave back into an electron, or is this some string theory level crap? 2: Can other wave types such as gravity or sound also be reversed into a corresponding particle? [ACTUAL EXPERIMENT QUESTION] 3: Can different charges besides the electric charge be used to generate any kind of field (positive/neutral), and if so what would that fields properties be? [OBJECTIVE] My objective is doing a simple little experiment in seeing what other methods exist in creating waves and measuring them. The problem lies in the fact that I'm unsure what kind of apparatus you would need to measure and set wave frequency, charge, etc... I also had a neat little idea wherein instead of somehow magically charging an object with electrons or protons I could just use cations and anions in some kind of liquid held in a test tube or something, to see if I could create a similar process, making this kind of a chemistry/physics combo. Maybe I'd use the negatively charged tube as my control group or something. So I'd appreciate any responses or input to my ideas here.. are they complete garbage, not doable in a home lab setting, or is my thinking way off? Basically the tl;dr is I'd like to know what (if any) devices I'd need to set this up. Thanks in advance!
