Propagation of Waves01:07

Propagation of Waves

2.4K
When a wave propagates from one medium to another, part of it may get reflected in the first medium, and part of it may get transmitted to the second medium. In such a case, the interface of the two mediums can be considered as a boundary that is neither fixed nor free.
Consider a scenario where a wave propagates from a string of low linear mass density to a string of high linear mass density. In such a case, the reflected wave is out of phase with respect to the incident wave, however the...

The de Broglie Wavelength

26.3K
In the macroscopic world, objects that are large enough to be seen by the naked eye follow the rules of classical physics. A billiard ball moving on a table will behave like a particle; it will continue traveling in a straight line unless it collides with another ball, or it is acted on by some other force, such as friction. The ball has a well-defined position and velocity or well-defined momentum, p = mv, which is defined by mass m and velocity v at any given moment. This is the typical...

Graphing the Wave Function01:13

Graphing the Wave Function

2.1K
Consider the wave equation for a sinusoidal wave moving in the positive x-direction. The wave equation is a function of both position and time. From the wave equation, two different graphs can be plotted.

Equations of Wave Motion

6.0K
Mathematically, the motion of a wave can be studied using a wavefunction. Consider a string oscillating up and down in simple harmonic motion, having a period T. The wave on the string is sinusoidal and is translated in the positive x-direction as time progresses. Sine is a function of the angle θ, oscillating between +A and −A and repeating every 2π radians. To construct a wave model, the ratio of the angle θ and the position x is considered.

Wave Parameters01:10

Wave Parameters

8.0K
The simplest mechanical waves are associated with simple harmonic motion and repeat themselves for several cycles. These simple harmonic waves can be modeled using a combination of sine and cosine functions. Consider a simplified surface water wave that moves across the water's surface. Unlike complex ocean waves, in surface water waves, water moves vertically, oscillating up and down, whereas the disturbance of the wave moves horizontally through the medium. If a seagull is floating on the...

Standing Waves01:17

Standing Waves

4.6K
Sometimes waves do not seem to move; rather, they just vibrate in place. Unmoving waves can be seen on the surface of a glass of milk kept in a refrigerator, which is one example of standing waves. Vibrations from the refrigerator motor create waves on the milk that oscillate up and down but do not seem to move across the surface. These waves are formed or created by the superposition of two or more identical moving waves in opposite directions. The waves move through each other, with their...

Area of Science:

  • Quantum mechanics
  • Foundations of physics

Background:

  • The wave function in quantum mechanics predicts outcome probabilities but not individual results.
  • This implies hidden variables may define specific experimental outcomes.

Purpose of the Study:

  • To analyze ensemble interpretations of quantum mechanics using hidden variables.
  • To propose a refined definition for ensemble interpretations.
  • To investigate the implications of local ensemble interpretations for statistical independence.

Main Methods:

  • Analysis of existing theorems and experimental results.
  • Examination of the ψ-ontic/epistemic distinction.
  • Investigation of statistical independence in local ψ-ensemble interpretations.

Main Results:

  • The ψ-ontic/epistemic distinction is inadequate for identifying ensemble interpretations.
  • All local ψ-ensemble interpretations reproducing quantum mechanics violate statistical independence.
  • Such theories exhibit superdeterminism or retrocausality.

Conclusions:

  • A refined definition of ensemble interpretations is proposed.
  • Local quantum mechanics implies violations of statistical independence (superdeterminism/retrocausality).
  • This interpretation offers insights into quantum phenomena like delayed choice and Wigner's friends.
