Duality Definition and 282 Threads

Oh, no. Another thread on Particle/Wave Duality? Forgive me for starting yet another thread on this topic, but I was just wondering if anyone had a different take on explaining this strange behavior. While I understand that light can behave in both modes, isn't it the observational...

1. I always thought that the word duality in QM referes to unmeasured (wave-like)/ measured (particle-like). So am I wrong? 2. Is that Marcella paper freely available on the net or another source that covers its content?

Consider a PRoblem in standard form; Max { Sum of (c_j * x_j) } Sum of (a_i,j * x_j) <= b_i , i = 1,...,m x_j >= 0 , j= 1,...,n Assume that x* = (x*_1,...x*_n ) is an optimal solution to this problem and that the first constraint is not satisfied at equality i.e. Sum of (a_1,j *...

Microscopic matter particles have associated wave functions, so do photons. The (probability) wave functions of photons are the classical EM waves. But don’t have EM waves another reality than matter probability waves? Isn’t the wave/ particle dualism of another kind for EM-waves/ photons than...

I have only taken an introductory course on QM so far, and a lot of it doesn't make sense to me. One thing that confuses me is what light is. In classical physics it was a wave consisting of oscilating electric and magnetic fields. In QM, I keep hearing about "wave-particle duality". My...

i was wondering, what if you shined two parallel rays of light directly next to each other and shot the particle throught them, one being a short wavelength and the other a long wavelength and measured each one. the first ray of light would find the momentum, so when u found the position you...

We are told since we are little kids that sounds are produced by vibrations/waves, these vibrations travel through a medium, such as air, until it reaches our ears, or until the vibrations lose strength and dissipate with distance. But what exactly causes these vibrations? Is it only the...

Does this describe wave particle duality correctly? 'Whether observed or not, a matter's wave particle duality still persist. The wave and matter characteristic cannot be isolated: A matter cannot be a wave sometimes and particle the other times. It must be both at anytime. However, when we...

This is my understanding towards wave particle duality: Matter is neither wave or particle.The matter position can only be determined when we observed the matter. When the matter is not observed, the matter can be in any position, and have a wave function. So, I make the following deduction...

This is one of the options I've found for IB extended essay topic. I would like to investigate and confirm the wave-particle duality of light. As an experiment to prove the wave nature I will shine a laser beam through a narrow slit, and use Heisenberg's Uncertainty Principle, \Delta p...

I was reading in one of my books today. It brought up an answered that I had when I was talking Modern PHysics over a year ago. Sadly our curriculum didn't really allow for us to do modern physics but our class flew through all the old physics for grade 12. Basically I had read a lot of...

I need some help understanding the nature of the wave in terms of QM. Many articles and papers seem to use the metaphor of a wave in water, though admiting its inadequacies. And I've seen models from victorian times that showed the wave in terms of a leading edge following a helix like...

just thought of this after watching a tv program on the origins of wave-particle duality discovery and the development of uncertainty theory. wonder if someone could bounce something back off me for it. now I am not a physicist, I am a computer science student, but I've read and watched a...

Hi all, Just wanted to clarify something in my head about the wave/particle duality of light. The fact that light is transmitted by photons, means that it can be described as a particle. While the wave nature comes out of the fact that the photons are distributed in a wave like manner...

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...

How would you prove that light is a particle rather than a wave? I understand that it is affected by black holes which proves it has mass but are there any other proofs? I'm sorry if this has been answered somewhere before.

I have a few questions about something I read in the http://pancake.uchicago.edu/~carroll/hawkingdublin.txt of Stephen Hawking's talk at GR17. He says that it has been claimed that the information paradox can be resolved by a duality between supergravity in anti de sitter (AdS) space and a...

In the wave particle duality a photon for example propagates as a wave but exchanges momentum as a particle. This looks a lot like what happens to a particle in QM, it has a spread (a wave property) wave function but when it interacts this collapses to a localised narrow 'spike' (a particle...

Instead of superstrings having 10 unitary dimensions (6 of compactified space and 3+1 of ordinary spacetime), imagine these 6 compactified spatial dimensions being of fractal value (3/6=1/2) relative to the 3 apparent dimensions of space. This corresponds as a dimensional duality to the 6...

The Booda cosmic isotropy duality hypothesis states: 1. Construct a spherical shell in spacetime. Mass-energy without and mass-energy within move overall to preserve their dual isotropic projection upon the shell, including position and apparent spin. 2. This hypothesis involves all...

M = E < C. Resolves duality of matter/energy characteristics of electrons and quantum level absorbtion/emmision characteristics of electrons.

Can Time and Space has Duality ? If only one dimension of space is considered together with time, can a duality exist for time and space? So that space looks like time and vice versa.

As the title implies, how does string theory describe the wave/particle duality of matter and the forces? How does it describe the double slit expirement? Thanks for the replies.

Hi, I'm looking for some help with a visual art project. Mainly does anyone have any ideas defining the diferences between discernment and duality with perception and an idea of singularity. Thankyou for your help and input.

My first article at http://www.quantumdream.net seeks to extend the quantum wavefunction to unexplored symmetric solutions. These obey the postulates of conventional quantum mechanics, but yield eigenvalues reciprocal to those accustomed. To construct the inverse from the traditional...

It has become almost axiomatic that whenever there is a discussion about the wave-particle duality of light it is inevitable that the double slit experiment is brought into the discussion as being the final and irrefutable proof of this property of the photon , since the existence of both wave...

I've never posted on here, or anywhere else for that matter, so bear with me per favore. (Disclaimer) I am somewhat discontent with words and our current understanding of how information flows, so I oftentimes use quotes around words because of that unreliability of what is sometimes...

Let's present a scale of frequencies of light. For initial we’ll take frequency of visible light. Here particle / wave duality is shown fifty- fifty. At increase or decrease of frequency this proportion is broken. Frequency increasing. Properties of a particle...

[SOLVED] Wave/Particle Duality in Light Quanta All right. It's a really simple concept to state, but a really difficult one to grasp. I'm curious about a specific experiment, if someone could explain it to me. The one slit/two slit experiment. With a constant stream of light and one razor-thin...

An interchange between variable action and Planck's constant in conventional wavefunctions represents a spectrum of virtual states that invert standard eigennumber solutions. The resultant "inverse wavefunctions" predict discrete values for virtual actions (in general those less than or...

I had a idea since where starting fresh.what if waves and particles acted as one instead of one at ant given time.what if a particle had a force acting on it from both sides of it as it travelled.since waves travel in curved paths i want to try to make particles travel in curved paths.up and...
