Relates particle momentum and its wavelength, or equivalently, energy and frequency.
The wavelength relation is:
λ=ph​
(1)
but since:
v=λfE=pv
(2)
the wavelength relation implies:
fv​=ph​f=hvp​=hE​
(3)
Particle wavelength can be for example measured very directly on a double-slit experiment.
So if we take for example electrons of different speeds, we should be able to see the diffraction pattern change accordingly.
