A beam of electrons is accelerated from rest through a potential difference of 0.100 kV and then passes through a thin slit. When viewed far from the slit, the diffracted beam shows its first minimum at ± 14.6° from the original direction of the beam. A) What is the velocity of the electrons? B) What is the de Broglie wavelength of the electrons?
