Problem

An X-ray photon with wavelength

0.050\,\text{nm}

scatters from a free electron and emerges with wavelength

0.055\,\text{nm}

. Neglecting any binding energy, what is the kinetic energy gained by the electron? a)

5.6\times10^{2}\,\text{eV}

2.3\times10^{3}\,\text{eV}

2.5\times10^{4}\,\text{eV}

1.8\times10^{3}\,\text{eV}
