Wave-particle duality

Quantum objects do not behave like simple tiny balls or classical waves. Both pictures capture only part of the observed behavior.

Core idea

Quantum objects do not behave like simple tiny balls or classical waves. Both pictures capture only part of the observed behavior.

Example

The de Broglie relation λ = h/p associates a wavelength with momentum, but it does not turn a particle into a classical material wave.

Common trap

A formula or trend is useful only when its definition and conditions of use are clear.

Check yourself

Explain the phenomenon in your own words, then identify which quantity or mechanism you would use to quantify it.
