A photon has a collision with a stationary electron (h/mc = 2.43 × 10^-¹² m)and loses 5.0% of its energy.The photon scattering angle is 180°.What is the wavelength of the incident photon in this scattering process? A)2.4 × 10^-¹² m B)4.6 × 10^-¹¹ m C)9.2 × 10^-¹¹ m D)1.9 × 10^-¹⁰ m E)3.1 × 10^-¹² m

The Compton wavelength shift formula is used: Δλ = h/mc (1 - cos θ). For θ = 180°, Δλ = 2h/mc. The energy loss of 5% implies a wavelength increase of 5%, leading to the calculation of the initial wavelength.
