Wave-Particle Duality

USUK
US/wave-particle duˈæləti/UK/wave-paticle duˈæləti/

Quantum objects exhibit both wave-like and particle-like properties simultaneously.

Also: de Broglie duality

Definition

Wave-particle duality is a fundamental concept in quantum mechanics stating that every quantum entity, such as an electron or photon, can exhibit both wave-like and particle-like properties. Which behavior is observed depends on the type of measurement or experiment performed. This principle was confirmed through experiments such as the double-slit experiment.

Example

In the double-slit experiment, electrons fired one at a time create an interference pattern on a screen, demonstrating their wave nature, yet each electron lands as a single discrete point, showing their particle nature.

Usage Examples

  1. 1

    The team applied wave-particle duality best practices to improve their physics outcomes significantly.

  2. 2

    Understanding wave-particle duality is essential for anyone building a career in STEM.

When & How to Use

Etymology & Origin

The term 'Wave-Particle Duality' derives from professional usage and entered STEM professional usage as the field formalised in the 20th century.

History & Evolution

The concept of wave-particle duality has evolved alongside STEM. Early practitioners relied on informal methods; structured approaches emerged with the professionalisation of physics in the mid-20th century. Today, wave-particle duality is a standard part of STEM practice globally.
