Question

As part of an electron diffraction experiment, electrons are accelerated from rest across a potential difference of 100 V.  The beam of electrons is then directed at a diffraction grating with 1000 lines/mm, and the resulting pattern is detected on a phosphorescent screen 0.25 m away from the grating.

The speed of the electrons is 5926738.977m/s

The wavelength of the electrons is 1.2279x10^-10m

what is the distance at which one would observe the 2nd maxima on the screen, as measured from the central maxima, using the formula 

λ = xd/nL,

where d=0.001mm, l=0.25m, n=2
