Why do we think particle is wave and probability also wave?

Click For Summary

Discussion Overview

The discussion revolves around the conceptual understanding of particles as waves and the wave-like nature of probability in quantum mechanics. Participants explore the implications of wave-particle duality, referencing experiments and theoretical frameworks while questioning the definitions and characteristics of these concepts.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • Some participants note that experiments like the double slit experiment demonstrate that particles exhibit wave characteristics, behaving as waves during travel and as particles upon interaction with matter.
  • There is a suggestion that the wavefunction, a solution to Schrödinger's equation, represents a wave of possibility rather than a classical wave, due to its complex values.
  • Questions are raised about the terminology used, specifically why the term "wave" is applied and whether amplitude corresponds to probability.
  • One participant expresses a view that the probability of observing a particle is wave-like, suggesting that a particle exists only when observed, otherwise remaining as potential.
  • Another participant refers to external resources, such as a FAQ, to address the particle/wave conundrum, indicating a desire for clarification on the topic.

Areas of Agreement / Disagreement

Participants express differing views on the interpretation of wave-particle duality and the nature of probability in quantum mechanics. There is no consensus on the definitions or implications of these concepts, and the discussion remains unresolved.

Contextual Notes

Participants highlight limitations in understanding wave-particle duality, including the dependence on definitions and the complexity of the wavefunction. Some assumptions about the nature of particles and waves are not fully explored or agreed upon.

Why do we think particle is wave and probability also wave?
If probability is wave,what is its wavelength,frequency,amplitude,period?
 
Physics news on Phys.org
The results of the experiments (e.g. double slit experiment) proved that the particles have some wave characteristics. So, our experience through these experiments shows that the particles behave as a wave when they travel and as particle when they interact with matter.

In classic physics it is impossible to define both wave and particle behaviour. Function Φ (which is the solution of Schroedinger's equation) cannot describe "something" natural, because its solutions are complex values. The only way to explain this problem was the statistic explanation. According to this explanation, the wavefunction is not a classical wave, but a wave of possibility.

Hey, let me refer you to our Physics FAQ where we have dealt with this particle/wave conundrum.

But why we call it "wave"?
And is its amplitude mean probability?

Didn't you read the FAQ. The term "wave" corresponds to a certain physical behaviour (eg interference, diffraction, etc etc) that can be explained mathematically by concepts like wavelength, etc etc. A particle can be described by these concepts because particles DO exhibit "wavelike" kind of physical behaviour. That is the basic idea

Illusive duality...

The probability of observing a particle is wave-like. This gives the particle its wave-like appearance. The particle only exists when it's observed, otherwise it's just potential. If I'm wrong on this interpretation, I hope to be corrected.
 
If your still not sure then perhaps this animated video will help:

There is also a few videos here (a little more detailed and not quite as entertaining):
