Electrons are accelerated through a potential difference $\mathrm{V}$ and protons are accelerated through a potential difference $4\mathrm{V}$. The de-Broglie wavelengths are ${\lambda }_e$ and ${\lambda }_p$ for electrons and protons respectively. The ratio of $\frac{{\lambda }_e}{{\lambda }_p}$ is given by: (given $m_e$ is mass of electron and $m_p$ is mass of proton).
