Relates particle
momentum
and its
wavelength
, or equivalently,
energy
and
frequency
.
The
wavelength
relation is:
λ
=
p
h
(1)
but since:
v
=
λ
f
E
=
p
v
(2)
the
wavelength
relation implies:
f
v
=
p
h
f
=
h
v
p
=
h
E
(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.
