If the potential difference used to accelerate electrons is doubled,by what factor does the de-Broglie wavelength associated with the electrons change?

  • A
    Wavelength is increased to $\sqrt{2}$ times.
  • B
    Wavelength is decreased to $\sqrt{2}$ times.
  • C
    Wavelength is decreased to $\frac{1}{\sqrt{2}}$ times.
  • D
    Wavelength is increased to $\frac{1}{\sqrt{2}}$ times.
