Double-slit experiment Definition and 115 Threads

Hi there, Let me start by introducing myself. I am a student who considers himself to be a very scientific thinker, that is to say, not one who believes in mystical thinking, but I am not studying physics. I am trying to learn more about this for my own edification (and I will try to be a...

The question goes like this, From the 2-slit interference experiment, determine the position of the 1st maximum if lambda=400nm, d=1mm and D=10cm. I've been reading through the experiment through external sites and none had given an example near the question. The question is, should i use...

Homework Statement Youngs double-slit experiment is performed with 589nm light and a distance of 2.00m between the slits and the screen. The tenth interference minimum is observed 7.26mm from the central maximum. Determine the spacing on the slits.Homework Equations Iavg = (Imax) cos^2 [(pi d...

[SIZE="1"]I'm not sure if "Quantum Physics" (or "Beyond the Standard Model") is the appropriate place for this question. Please move if necessary. What does "Quaternion Quantum Mechanics" say about the famous double-slit experiment? Does it make the same quantitative prediction as standard...

I am planning to recreate the Double-Slit experiment for my senior project (in HS) and I've tried searching many sites on how to go about doing this but I couldn't find anything relevant. Does anyone know a site (or book) that would tell me the materials I need to make the experiment and how...

Question: Coherent light with wavelength 400 nm passes through two very narrow slits that are separated by 0.200 mm and the interference pattern is observed on a screen 4.00 m from the slits. A What is the width (in mm) of the central interference maximum? y_m = R \cdot \frac{m \cdot...

Ok, I have a handful of questions: 1. Particles A and B are entangled, measuring A colapses the wave function of B, right? 2. The double-slit experiment produces different outcome based on whether or not a particle has been measured, right?

I'm having problems with the following problem: A rock concert is being held in an open field. Two loudspeakers are separated by 9.00 m. As an aid in arranging the seating, a test is conducted in which both speakers vibrate in phase and produce an 80.0 Hz bass tone simultaneously. The speed...

Consider the double-slit experiment with electrons. It is so, that observing trough which split the electron goes will destroy the interference pattern. This can be seen in a thought experiment in which one adds a light source near the splits. One can calculate that as soon as the...

What will we see on the screen in double-slit experiment if I use two radiation have wavelength l_1 and l_2 . I know there will be two systems of interference fringe, call I and II. But what if one light region of I is coincident one dark region of II ? And then how many light regions do we...

Light Waves & Double-Slit Experiment Question... Our professor gave us an extra credit question on our last quiz & every single student got it wrong, all 150 of us! Anyways, here is the question, if you know the answer that would be greatly appreciated. Here is the question: Describe in as...

I am asked to construct a double-slit experiment for 5eV electrons. The first minimum of the diffraction pattern needs to occur at 5 degrees, what must the separation of slits be? I'm guessing that I should use Bragg's law but I don't know how to calcualte a minumum because bragg's law is for...

I found some very entertaining presentations of the Double-Slit Experiments at ... http://www.colorado.edu/physics/2000/schroedinger/index.html ... and it made me start thinking. The "professor" presents an example of someone shooting a machine gun through the two slits and the "student" asks...

Hello. I just have some questions about Young's Double-Slit experiment and light wave interference. I think i got the right answers, but i just want to know if i grasped the concept correctly. 1-If we perform young's double slit experiment under water, how would the interference pattern be...

Gerhard Paulus of Texas A&M University and co-workers in Berlin have developed a new look for Young's double-slit experiment. Interference pattern has been observed with electrons that pass through a double slit in time, not space, as a result of being ejected from an atom at one of two possible...
