Davisson-Germer, Uncertainty, Compton & X-Rays

The minimum wavelength of the X-rays produced by electrons accelerated through a potential difference of VV volts is directly proportional to

Show answer and solution

Answer: (b)

  1. Cut-off condition: eV=hcλmineV = \frac{hc}{\lambda_{min}}.
  2. λmin=hceV⇒λmin∝1V\lambda_{min} = \frac{hc}{eV} \Rightarrow \lambda_{min} \propto \frac{1}{V}
  3. So the answer is (b) 1V\frac{1}{V}.
