Answer:
de Broglie's wavelength.
Explanation:
de Broglie's wavelength.
The de Broglie formula is the equation used only to explain the wave characteristics of matter, namely the wave existence of the electron:
λ = h / mv,
where λ is wavelength, h is Planck's constant, m is a particle's mass, traveling at a velocity v.
de Broglie proposed that matter particles can exhibit wave characteristics.
