Through what potential difference AV must electrons be accelerated (from rest) so that they will have the same wavelength as an X-ray of wavelength 0.145 nm ? Use 6.63x10-34 J·s for Planck's constant, 9.11x10-31 kg for the mass of an electron, and 1.60x10-19 C for the charge on an electron. Express your answer using three significant figures. ► View Available Hint(s) ΙΙ ΑΣΦ ? AVDelta V = V
