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

Options

  1. AWavelength increased two times
  2. BWavelength decreased to half
  3. CWavelength increased four times
  4. DWavelength remains the same

Correct answer

B. Wavelength decreased to half

Step-by-step solution

array ll & 1 ~V & ₂ ₁ = V ₁ ~V ₂ array Given that, V ₂=4 ~V ₁ ₂= ₁ V ₁ 4 ~V ₁ = ₁ 2
