PX262 - A5 - debroglie waves

if light can behave as a particle, can particles also behave as waves?
debroglie proposed that particles can behave as waves, and are assigned a frequency and a wave number:

\begin{matrix} E = ℏ ω, where (ω = frequency) \\ \vec{p} = ℏ \vec{k}, where (\vec{k} = wavenumber vector) \end{matrix}

in a double slit experiment, electrons are shot though a double slit and on a screen behind, typical wave interference pattern can be observed
