==Key Stage 5==
===Meaning===
The [[de Broglie wavelength]] is the [[wavelength]] associated with a particle and is inversely proportional to its momentum, demonstrating the wave-like nature of matter.
===About de Broglie Wavelength===
Given by the formula
𝜆
=
ℎ
𝑝
λ=
p
h
, where
𝜆
λ is the wavelength,
ℎ
h is the [[Planck constant]], and
𝑝
p is the momentum.
Suggests that [[particle]]s such as [[electron]]s have [[wave]] properties.
Confirmed by experiments such as electron diffraction through a crystal.
Fundamental to the development of quantum mechanics.
The concept applies to all particles, including macroscopic objects, but the [[wavelength]] is significant only for very small [[particle]]s like [[electron]]s.
===Formula===
:<math>~ E= h \nu , \qquad </math> <math>~c= \lambda \nu , \qquad </math> <math>~ E= \frac {hc} {\lambda} = pc, \qquad </math>
===Examples===
Electrons showing diffraction patterns when passing through a thin crystal.
The de Broglie [[wavelength]] of a moving car is extremely small and not observable.
