Two slit experiment Definition and 26 Threads

It's obvious that the Observer Effect can take place without conscious observation, for example with a photon and electron out in the wild, but I'm trying to find a single study which disproves the role of conscious measurement within the observer effect. An experiment which I think would...

Examples that have references to special two slit experiments : https://sciencedemonstrations.fas.harvard.edu/presentations/single-photon-interference https://en.wikipedia.org/wiki/Double-slit_experiment If you have an opinion on what you think the experiments tend to support and what they do...

If the two slit experiment is performed with one slit half the width -- or 1% or 0.1% the width -- of the other, how is the interference pattern affected.

This is based on the Hugh Everetts interpretation of quantum mechanics, where the waveform never collapses but the observer becomes a part of it, thus experiencing decoherence of the wave form from their point of view. So, let's say someone is doing the two-slit experiment. The particles going...

Homework Statement How do I know what value of m to use when using the equation? Here we had to use m = 1 to find the answer. Please refer to part 3 for the problem statement. Homework Equations Please refer to part 3 for the relevant equations. The Attempt at a Solution [/B]

Would it be theoretically possible to perform a two slit experiment with, say, baseballs? How would such an experiment need be set up?

regarding Young's two slit experiment 1. HOW can a light source is used to create a single photon that can be directed at 2 slits simultaneously ? I am confused as to how the light source can be aligned with both of the slits simultaneously. IF the light beam is wider than the distance...

Is it possible that the reason the delayed choice two slit experiment outcomes occur is because for the photon, traveling at the speed of light, the past, present and future are all as one, and therefore it "knows" what is going to happen and therefore always "makes the right choice" at the...

There seems to be two divided approaches in how the uncertainty principle is explained, but they seem to be explaining two different things. The first, more intuitive explanation of the limits imposed by quantum mechanics goes something like: in order for a measurement to be made, we have to...

I was wondering if the two slit experiment has been performed with a wavy screen, the screen being modulated in such a way as to compensate for the difference in the phases of the paths from the two slits. If so what was the result in terms of the angular distribution? If not what would it be...

I understand the two slit experiment and the outcome, but where I am confused is how the detectors work. It seems to me that a very simple explanation of the result differing due to the presence of the detectors is that somehow the detectors interfere with the path of the electrons. By...

Hello! I have questions in regards to the Two Slit Experiment. If the photon splits in two and passes through both slits at the same time and interferes with itself on the other side of the screen and then it hits on the second screen thereby creating the interference pattern. At what point...

A couple of days ago i stumble across the two slit vid on youtube and entanglement. before this day i thought quantum physics was just some kind time travel mumbo jumbo ... I am sure you get my level of noobieness from this :) ok questions if you would be so kind :) ( don't forget the...

Why is it possible to do this experiment at home and still see light as a wave? Isn't there loads of interference? Or does this have to do with wavelength? If you use a laserpen and 3 needles you can basicly do it at home without shielding off anything...

Hi all! I heard about that the experiment had been iplemented so the observation don't effect the experiment. Because some scientists thought that the observation has an effect on the experiment and that's why the interference pattern doesn't appear at that time. My question is, how they do...

Question: I'm sure this is a stupid question, but it has been bothering me lately so I'll ask it anyhow. In Young's Two Slit experiment the conditions for max and min are dsin\theta=m\lambda (max) dsin\theta=(m+\frac{1}{2})\lambda (min) where m is an integer and d is the separation of the...

In the two slit experiment when which path information is present there is no wave interference pattern such as would be seen with both slits being used. When a single slit is used there is a visible diffraction pattern. Is such a pattern seen when a detector forces a one slit path in the two...

Hi. Firstly, I'm not a physics student but was just wanting some answers to questions from those that are, so I thought I'd try you lot. :smile: 1. Has anyone proved that quantum entanglement doesn't happen at the macro level? 2. Regarding the 2 slit experiment and how consciousness...

I have a question about the situation with the two slit experiment where detectors are placed by the two slits to determine which slit the particle has gone through (and destroy the diffraction pattern). Okay, so what I'm wondering is what happens if the detectors' accuracy is not fixed, but...

Homework Statement Red light with wavelength of 700 nm is passed through a two slit apparatus. At the same time, monochromatic visible light with another wavelength passed through the same apparatus. As a result most of the pattern that appears on the screen is a mixture of two colors...

can anyone give imput please,i have a problem with Youngs two slit experiment,if i remove the lens from the laser,you just get the 2 slits, iv got a few videos of it on youtube you might find strange

I am trying to understand the essentials of the Bohmian interpretation of quantum mechanics (BI),and my (many) difficulties start with his description of the two slit experiment.As I understand it,Bohm asserts that every quantum particle has associated with it a quantum potential or guiding...

The number that comes up on a die seems to be determined by mechanics - not probability; eventhough dice are used to explain probability. Is there a analogus process that determines where a photon will fall in the double split experiment - eventhough it is explained by probability?

The 2 slit experiment is common, but what exactly is the complete setup. i know the interference patterns, but there are variables in every experiment. Where is the particle fired? Is it fired precisely at one of the slits, or is it fired so that it should hit in between the two slits if...

electron two slit experiment with gradual "collapse"? Just read about the two slit experiment with electrons where you try to find out through which slit the electron went by "shining a light on it" (Feynman lectures on physics I-37-7). I try to summarize the statement and then have a question...

Hi, I'm new and I'm from Poland. I have problem with equation(average number of photons registered behind pinhole 1 in two slit experiment): \bar{n}_1=\langle n|a_{1}^{+}a_{1}|n\rangle=\frac{\langle 0|(a^{+})^{n}a_{1}^{+}a_{1}(a^{+})^{n}|0\rangle}{n!} using...
