The de Broglie Wavelength02:32

The de Broglie Wavelength

30.0K
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...

The Uncertainty Principle

28.1K
Werner Heisenberg considered the limits of how accurately one can measure properties of an electron or other microscopic particles. He determined that there is a fundamental limit to how accurately one can measure both a particle’s position and its momentum simultaneously. The more accurate the measurement of the momentum of a particle is known, the less accurate the position at that time is known and vice versa. This is what is now called the Heisenberg uncertainty principle. He...

The Quantum-Mechanical Model of an Atom

52.4K
Shortly after de Broglie published his ideas that the electron in a hydrogen atom could be better thought of as being a circular standing wave instead of a particle moving in quantized circular orbits, Erwin Schrödinger extended de Broglie’s work by deriving what is now known as the Schrödinger equation. When Schrödinger applied his equation to hydrogen-like atoms, he was able to reproduce Bohr’s expression for the energy and, thus, the Rydberg formula governing hydrogen spectra.

The Bohr Model

73.0K
Following the work of Ernest Rutherford and his colleagues in the early twentieth century, the picture of atoms consisting of tiny dense nuclei surrounded by lighter and even tinier electrons continually moving about the nucleus was well established. This picture was called the planetary model since it pictured the atom as a miniature “solar system” with the electrons orbiting the nucleus like planets orbiting the sun. The simplest atom is hydrogen, consisting of a single proton as...

Space-Time Curvature and the General Theory of Relativity

3.3K
In 1905, Albert Einstein published his special theory of relativity. According to this theory, no matter in the universe can attain a speed greater than the speed of light in a vacuum, which thus serves as the speed limit of the universe.
This has been verified in many experiments. However, space and time are no longer absolute. Two observers moving relative to one another do not agree on the length of objects or the passage of time. The mechanics of objects based on Newton's laws of...

Thomson's e/m Experiment

5.0K
In a beam of charged particles created by a heated cathode, the particles move at different speeds. However, many applications need a beam with uniform particle speeds. An arrangement known as a velocity selector uses electric and magnetic fields to pick particles with a particular speed from the beam.
A particle with charge q, speed v, and mass m enters an area from the top, where the magnetic and electric fields are perpendicular both to the particle's motion and to one another. The...

Area of Science:

  • Quantum mechanics
  • Quantum entanglement
  • Foundations of physics

Background:

  • Quantum mechanics predicts correlations exceeding classical limits of locality and realism.
  • High quantum correlations may enable faster-than-light signaling, restricting nonlinear evolution operators.
  • A hypothesis suggests these correlations develop over time L/c.

Purpose of the Study:

  • To propose and describe a hidden variables model based on modified Wheeler-Feynman theory.
  • To investigate if quantum correlations evolve over time, respecting locality and realism at shorter intervals.
  • To propose an experimental test for this hypothesis.

Main Methods:

  • Development of a hidden variables model rooted in modified Wheeler-Feynman radiation theory.
  • Proposal of an experiment using a pulsed entangled source and stroboscopic particle detection.
  • Analysis of existing optical experiment data for consistency with the model.

Main Results:

  • A hidden variables model consistent with the temporal evolution hypothesis is described.
  • Analysis of incomplete optical experiments shows results compatible with the proposed model.
  • The hypothesis remains experimentally unrefuted by current data.

Conclusions:

  • The proposed model and hypothesis offer a potential resolution to the conflict between quantum correlations and classical realism.
  • While preliminary data is consistent, a complete and specific experimental test is crucial for validation.
  • Further research is needed to definitively test the temporal development of quantum correlations.
