Problem

The de Broglie wavelength of non-relativistic electrons in a beam is measured to be

0.50\,\text{nm}

when their speed is

3.0 \times 10^{6}\,\text{m s}^{-1}

. Estimate the wavelength when their speed is increased to

6.0 \times 10^{6}\,\text{m s}^{-1}

, assuming all other factors remain unchanged.
