Double slit Definition and 825 Threads

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...

Hello all, I saw this setup for a quantum eraser: http://grad.physics.sunysb.edu/~amarch/PHY5656.gif In this setup, we get no interference: http://grad.physics.sunysb.edu/~amarch/PHY5658.gif Then, by inserting a polarizer we can erase the which way information: Setup with...

Recently Paulus and his team had reported observation of interference in time. http://physicsweb.org/articles/news/9/3/1/1?rss=2.0 http://arxiv.org/pdf/quant-ph/0503165 It is a marvellous experiment. But, it appears the work is not fully explained and the experimental results need careful...

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...

Anyone know where to find some well documented Double slit experiment results? Thorough and complete detailed information on all parts: Wavelength used, width of slits, separation of slits, Distance from slits to detection screen or film. Flat screen or detail on a curve in detection...

A monochromated beam of neutrons (speed 0.40 m/s) is directed through a double slit with 1.0 mm separation. An array of detectors is placed 10m from the slit. a)what is the de Broglie wavelength of the neutrons? b)how far off-axis is the first zero-intensity point on the detector array...

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...

Interesting take on Young's experiment... http://physicsweb.org/articles/news/9/3/1/1?rss=2.0 wonder what that does to Mr. Deutsch's Multiverse?

Hello, I wondered how one treats the double slit experiment quantum mechanically, that is, using probability amplitudes,wave functions,etc...to calculate the intensity on the screen. If anyone knows a link or a paper or a book where I can find it, that'd be nice. -Edgardo

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...

single slit problem (simple) A single slit diffracts laser light of wavelength 610 nm onto a screen 3.25 m away. The distance between the two first-order maxima on either side of the central peak is 3.65 mm. How wide is the slit (in mm)? I figured the formula \lambda m = d sin(\theta) would...

Hi, just need a quick confirmation I am right with something! :) If we are considering electrons (for example) going through the double slit experiment one at a time would it be correct to define the wavefunction for the electron as follows? \Ket{\Psi} = C_1\Ket{\phi_1} + C_2\Ket{\phi_2}...

"In Young's double slit experiment, assuming the distance between the slits is 0.07mm and the wavelength of light used is 600 nm, when the screen is 70 cm away, what kind of interference is there." I'm not sure what I'm being asked to determine here. Plugging in the figures into the...

I've been puzzling over the two-slit experiment. There's an alternate setup where you use lasers and prisms. [A laser beam is split with a half-silvered mirror/prism. Photons take one path or the other and hit one of two detectors. We arbitrarily insert a converging mirror/prism near the end...

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 suppose someone has thought of this but is the supposed "interference" of light particles in the double slit experiment actually only the apparent interference of light particles and actually an interference of paths open for the light particles to travel? I. e. it is something else creating...

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...

Double slit arrangment?? Can anybody help me with this problem? A thin flake of mica(n=1.58) is used to cover one slit of a double slit interference arrangment.The central point on the viewing screen is now covered by what had been the 5th bright fringe before the mica was used. Find the...

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 found that blue light of wavelength 478 nm gives a second-order maximum at a certain location on the screen. What wavelength of visible light would have a minimum at the same location? ----- I have no clue how to approach this problem but looking in 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?

Greetings ! I see that my original thread called "Uncertain Gravity?" did not get the attention that I hoped it would (a level at least sufficient to answer the question I'm now separately posting here). So, the question: What does modern physics say about the double slit experiment...
