The de Broglie wavelength associated with an electron, accelerated by a potential difference of 81 ~V is given by:

Options

  1. A1.36 ~nm
  2. B0.136 ~nm
  3. C13.6 ~nm
  4. D136 ~nm

Correct answer

B. 0.136 ~nm

Step-by-step solution

We know, for an electron De Broglie wavelength, = 12.27 v Å aligned & = 12.27 81 = 12.27 9 Å & =1.36 Å or 0.136 ~nm aligned
