  1. Question 1

    Q1. The wavelength of an electron accelerated through a potential difference V is

    • A) √(150 / V) Å
    • B) √(150 * V) Å
    • C) √(V / 150) Å
    • D) √(1 / (150 * V)) Å

    Answer: √(150 / V) Å

    Explanation: The de Broglie wavelength of an electron accelerated through a potential V is given by λ = √(150 / V) Å.
