  1. Question 1

    Q1. An electron is accelerated through 100 V. What formula calculates its de Broglie wavelength?

    • A) λ = h/(√(2meV))
    • B) λ = h/(mv)
    • C) λ = h/(mc)
    • D) λ = hc/V

    Answer: λ = h/(√(2meV))

    Explanation: Relativistic acceleration uses √(2meV). Option B assumes classical velocity.
