de broglie wave
C1Technical / Academic
Definition
Meaning
A quantum mechanical concept describing the wave-like behavior of particles, such as electrons or protons.
The wave associated with any moving particle, with a wavelength inversely proportional to its momentum, central to wave-particle duality in quantum mechanics.
Linguistics
Semantic Notes
Always capitalised ('de Broglie') as it originates from a surname. Primarily a physics term with no metaphorical extensions in common language.

Examples
By Part of Speech
adjective
British English
- de Broglie wavelength
American English
- de Broglie wavelength
Examples
By CEFR Level
- Electrons can behave like waves, a property described by the de Broglie hypothesis.
- The electron's de Broglie wavelength must be considered when designing nano-scale transistors.
Learning

Mnemonic
de Broglie (pronounced 'de Broy') thought particles could be WAVEY.
Conceptual Metaphor
A moving particle is like a ripple on a pond.

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid literal translation. Use established term 'волна де Бройля'.
Common Mistakes
- Incorrect capitalisation (e.g., 'De broglie wave', 'de broglie Wave')
- Mispronunciation of 'Broglie' (not 'Broggle')

The French physicist Louis de Broglie in his 1924 PhD thesis.
λ = h / p, where λ is wavelength, h is Planck's constant, and p is momentum.
They are probability waves, describing the likelihood of finding a particle in a given location, not a physical displacement like water waves.
The Davisson-Germer experiment (1927) demonstrating electron diffraction confirmed the wave nature of electrons.
