Dual Nature Of Radiation

An \(\alpha\)-particle and a proton are accelerated from the rest by a potential difference of 100 V. After this, their de Broglie wavelengths are \(\lambda\)_\(\alpha\) and \(\lambda\)_p, respectively. The ratio \({{{\lambda _p}} \over {{\lambda _\alpha }}}\), to the nearest integer, is _____________.
