    Count Coulombs on a Plate: Best Charge Methods

    Also, wouldn't the control capacitor leak after I disconnected it to measure its voltage?

    Count Coulombs on a Plate: Best Charge Methods

    I know that the single-plate one logically connects to ground through the air; what I meant was: Would the capacitance it could have being that far from a ground be at all significant? My current setup requires a single plate with one charge (the polarity doesn't matter, although I hear...

    Count Coulombs on a Plate: Best Charge Methods

    Is it really that simple?! That's because of Kirchoff's circuit equations (eg, constant current in series), right? So you're saying something like http://rprogrammer.net/static/curios/Monoplate_charger.gif or http://rprogrammer.net/static/curios/Biplate_charger.gif The first one...

    Count Coulombs on a Plate: Best Charge Methods

    What is the best way to put a charge on a plate? By 'plate' I mean some mass of conductor surrounded by an insulator. The problem, really, isn't how to generate charge, I know I can use a Van de graff or high-voltage rectifier for that; the problem is that I need to be certain of how much...

    Distance between each double-slit and the light band.

    I don't have a textbook, I'm just going over the questions I missed online. I've gotten all of them except this one. If you could just point me in the right direction, I would be most grateful.

    Distance between each double-slit and the light band.

    Homework Statement http://img225.imageshack.us/img225/3118/photo1587hx4.jpg This #74 is on the SAT Practice Subject Test in Physics, which is also the Physics test administered in January 2003. Homework Equations I don't even know how to begin this problem. The Attempt at a...

    Can Extending the Delay in a Quantum Eraser Experiment Alter Past Events?

    Confusion Ok, now I think I've been confused all this time. Here's how I thought the measurement was taken (of the signal photons, D0 in the paper): The signal photons either exhibited a particle or a interference tendency (although only to be seen over meny repetitions). D0 was on a...

    Can Extending the Delay in a Quantum Eraser Experiment Alter Past Events?

    Signal vs Idler Sorry, you had them correct JesseM, The signal is measured by the detector, and the idler is put through the choice.

    Can Extending the Delay in a Quantum Eraser Experiment Alter Past Events?

    Gaussian So if you look at the detector prematurely you see noise? Because if you always see noise this isn't much of an experiment.

    Can Extending the Delay in a Quantum Eraser Experiment Alter Past Events?

    Which pattern? Now take a modification of the experiment where many photons are sent to the interferometer and hit the detector so that a pattern could emerge (and those are the idlers?). While the signal(?) photons are still traveling for such a time that the last idler has hit the detector...

    Can Extending the Delay in a Quantum Eraser Experiment Alter Past Events?

    Understanding Bohmian Demystifier So, under the bohmian interpretation of quantum mechanics, every particle is a particle and a wave always. And that the wave influences the particle based on where the wave is most intense. But does that mean manipulating the which-way information...

    Can Extending the Delay in a Quantum Eraser Experiment Alter Past Events?

    Simplification I too have seen this a lot and have found a one-line version of the question: What would you see if you looked at the detector in a DCQE before the choice was made? Now as for the implementation, I see Spacezilla's point also that the implementation would seem at least...

    Questions on Entanglement and Double-Slit Experiment

    My point So, what all this has been leading up to is this: I have heard numerous places that Faster Than Lishgt information transfer cannot be achieved. So, I would like to further my understandings of quantum physics from someone explaining to me what prevents this scenario from...

    Questions on Entanglement and Double-Slit Experiment

    Last question.. (Hopefully) One (hopefully) final question: E. In the double slit experiment, would an interference pattern develop if a third party knew, or could know which slit the particles went through?
