Double slit experiment Definition and 484 Threads

Hi, We all know that when we shoot electrons one by one on an apparatus having two slits then it forms a interference pattern. Means this implies that the electron passes through both the slits at the same time Now when we keep a detector near the slits to watch the...

I am doing a presentation for my high school physics class on light. I want to show the wave-particle duality of light, but first I want to show each separately. So I want to introduce Young's Double Slit Experiment to show the wave nature of light. The problem is... I apparently don't know...

If you take the normal double slit experiment but shine light on one of the slits so that it's possible to tell which slit each electron went through (by detecting scattered photons) then the "fringes" disappear amd you get constant light. If before the scattered photons hit the photon detector...

Hi, I would like to know what would happen if we altered one of the slits by making it into a very very long tunnel (an optical cable that would run for a significant distance, but would come out on the other side of the screen almost in the same spot of its beginning). Would this destroy...

Homework Statement in a double-slit experiment, blue light of wavelength 4.60*10^2 nm gives a second order maximum or CI at a certain location P on the screen. what wavelength of visible light would have a minimum or DI at P? Homework Equations x=(l*lamda)/separation The Attempt at...

Homework Statement A very thin sheet of plastic (n = 1.45) covers one slit of a double-slit apparatus illuminated by 570 nm light. The center point on the screen, instead of being a maximum, is dark. What is the (minimum) thickness of the plastic? Homework Equations Constructive...

A monochromatic, coherent light source is targetted through a pair of double slits, and produces a series of small dots on a background screen. According to Young, this is caused by the interference of light wave trains, constructively and destructively interfering to produce antinodes and nodes...

Homework Statement # It is given in my book that if white light is used instead of monochromatic light, the central fringe will be white while there will be coloured fringes on either side of the central fringe. Could anyone please tell me the reason for this? Is it because, due to...

Hi; I'm new to the forum and I hope my question is not out of line. Has anyone ever done double slit experiments with macroscopic objects such as grains of sand, for instance. It seems to me that with appropriately sized and spaced slits in a mask of appropriate thickness, one should be able...

Hi, I've done a few terms worth of quantum mechanics, which was good on explaining the mathematics, but not good at explaining it's "derivation". I've been reading the Feynman lectures, and I've learned a hell of a lot. It does seem though, the more I learn, the less I understand . But it's...

I have a question that's been buggin me as I've built an interest in what kind of part does consciousness play in quantum mechanics. My question is if anyone has conducted the Double slit experiment, in a way that the measuring device(s) at the slits (that determine which slit it goes...

Hello all, I have a problem that requires some knowledge about Young's double slit experiment. The question is as follows: Imagine performing Young's experiment with one slit wider than the other so that the intensity passing the wider slit is four times as great as that passing the narrower...

I'm only a first year psychology student, so I appologize for my lack of understanding. But looking at the double slit expirament described in Feynmans book QED, for example, where two slits separate a photon emitter and detector, where the separation distance of the slits determines how many...

I have an advanced amateur's(if there is such a thing) grasp of the concepts of quantum physics. However, the typical usage of the 'double slit experiment' to explain an observation of the differences between classical and quantum behaviours confuses me. The specific case, of course, is when...

Hi... Could anyone please tell me that why does the intensity of the interference pattern get diminished towards the ends of the screen ? And can anyone also tell me what is the theoretical number of maxima that can be obtained in YDS experiment for a given wavelength, and slit , screen...

Hi, Could somebody, please, give a reference for the exact derivation of the single-photon double-slit experiment? I mean similar then the well-known solution for the particle-in-box, or for the Hydrogen-atom. That is, starting from the Schrödinger-equation, taking boundary conditions...

Hi! :smile: I’m new here and enjoying it very much. In the double slit experiment; what causes the fired electron to change from being in a wave configuration, back to a particle configuration when it strikes the target? Mizpah

I stumbled upon this, basically what i want to know is. Does a single electron shot through two slots produce an interference pattern? When you observe which slot the electron goes through does the act of observing prevent it from producing an interference pattern?

hello, i am doing a work sheet on the title of this thread and i do not have the answer sheet for the questions so can some one please go through my answers and see if i am correct Young used a monochromatic light source a) wat does this mean? my ans: light of a single wavelength b)...

From what I know of the double slit experiment you shine a light at two different slits and half of the photons go through one, and the other half go through the other (or a ratio similar to that), and i am pretty sure the second part of the experiment is to shoot one photon at the two slits and...

For the Young's Double slit Experiment, I'm just wondering when it comes to finding the distance between the adjacent fringes (shown on the screen), why can't we just measure directly the distance between the adjacent fringes instead of having to measure the distance between 5 fringes and...

I have read that if you set up a double slit experiment and let photons go through one at a time they build up an interference pattern. I have also read that this interference pattern is similar to having a pool with two wave generators on one side of the double slit and looking at the...

How will the Fringe system in a Young's double slit experiment affected if, 1] a pair of polarising sheets P1 and P2, one before each of the slits S1 and S2, such that their transmission directions are parallel. 2] what will be the effect if the transmission lines are mutually orthogonal...

Hey guys, I was reading, as you do, a bit of physics on the classic double slit experiment - this was a simple example that was in the article, however it got me thinking. I remember reading about some physicsts performing the experiment with electrons. now I also think I remember that...

ok so I read this book recently, timeline. In it they explain an experiment I've heard about a lot in physics. However, they gave a very strange look at it that I can't figure out. Basically, its the double slit experiment except instead of using light waves / many photons, you use particles...

I just posted this as a reply, but i figured Id open a new thread for discussion. correct me if I am wrong here. according to the double slit experiment, a photon takes every possible path to it's destination, causing it to interfere with itself, right? My first question is, does each...

I once read about a modified double slit experiment where the distance between one slit and the source was different to distance between the other slit and the source. It gave the usual interference result, and showed the common feature of other double slit experiments, equal distances to both...

Double slit experiment IN TIME ! The famous double slit experiment performed in another way ... The slits are not in space but in time : two positive peaks and one negative peak of an electric field contained in a very short laser pulse...

I just have some narrow questions and got a headache searching through the other threads to see if they have been answered. I just want to understand more specifically what is actually going on with the detectors at the slits. 99% of the explanations and descriptions I read about just talk...

What would be the best set up to repeat Young's double slit experiment with a diode laser?

there's something that is annoying me, because I can't find a explanation It's about the classical double slit experiment, where you have two screens, and one of them has 2 narrow slits then you launch a photon against the screens, and if there are no detectors in the slits, you observe an...

I have decided on a physics experiment for high school, but am not sure how to go about doing it, and what materials to use :confused: . Its called the Single photon Double Slit Experiment, similar to the one done by GI Taylor, years ago. the basic concept is that a single photon is...

This experiment which is a variation of the double slit experiment , has actually been conducted. We have (a) the source of electrons, (b) screen 1 ( with the double slit ) and finally (c) screen 2 , where the particles are registered. Near the slits in screen 1 and on the far side from the...

In a double slit experiment it is observed that the distance between adjacent maxima on a remote screen is 1cm. Whats happens to the distance between adjacent maxima when the slit separation is cut in half?
