(N/A) The de-Broglie hypothesis states that all material particles in motion possess wave-like properties.
According to this hypothesis,a particle of mass $m$ moving with a velocity $v$ has an associated wavelength $\lambda$,which is given by the relation:
$\lambda = \frac{h}{p} = \frac{h}{mv}$
where:
$h$ is Planck's constant,
$p$ is the linear momentum of the particle,
$m$ is the mass of the particle,
$v$ is the velocity of the particle.
This suggests that matter exhibits a dual nature,behaving both as a particle and as a wave.
