Problem

A photon of frequency

5.00\times10^{18}\,\text{Hz}

scatters from an initially stationary free electron. The scattered photon’s frequency is

4.88\times10^{18}\,\text{Hz}

. Treating the electron non-relativistically, what is the speed of the electron immediately after the collision? (a)

7.2\times10^{6}\,\text{m/s}

(b)

1.3\times10^{7}\,\text{m/s}

(c)

9.4\times10^{6}\,\text{m/s}

(d)

4.2\times10^{6}\,\text{m/s}
