  1. Question 1

    Q1. A photon of wavelength 0.1 nm collides with an electron at rest. If the scattering angle is 60°, what is the change in wavelength? Use λ' - λ = (h/m_e c)(1 - cosθ)

    • A) 2.43 pm
    • B) 1.22 pm
    • C) 3.64 pm
    • D) 4.86 pm

    Answer: 1.22 pm

    Explanation: Compton shift formula gives 1.22 pm. Option D doubles the correct value.
