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. a) whats the speed of the electrons as they reach the diffraction grating? b) whats the wavelength of the electrons? c) what is the distance at which one would observe the 2nd maxima on the screen, as measured from the central maxima?
