A number of electrons are accelerated from rest through a potential difference V. They are then incident on a double slit setup with slit spacing d = 47.4nm. The m= 494 order maximum for this pattern is observed at 8 = 10.8° from the normal to the slits. Part 1) What is the wavelength of the electrons? A = Part 2) What is the momentum of this electron? kgm/s P= Part 3) Making the approximation that relativistic effects are negligible, what is potential difference, V, through which the electrons were accelerated? V
