- An electron is accelerated from rest through a potential difference of 100 V. What is the de Broglie wavelength of the electron?An electron is accelerated from rest through a potential difference so that its de Broglie wavelength is 0.020 nm. What is the potential difference?The nucleus of an atom is on the order of 10-14 m in diameter.
