  1. Question 1

    Q1. The Compton shift in wavelength is given by Δλ = λ' - λ = (h/m_ec)(1 - cosθ). What does 'm_e' represent?

    • A) Mass of the electron
    • B) Mass of the photon
    • C) Mass of the proton
    • D) Mass of the neutron

    Answer: Mass of the electron

    Explanation: m_e is the rest mass of the electron; it's a key parameter in Compton scattering.
