A) 5.68 pm
B) 7.42 pm
C) 3.28 pm
D) 0.868 pm
E) 2.43 pm

The Compton wavelength shift formula is $\Delta \lambda = \lambda' - \lambda = \frac{h}{m_ec}(1 - \cos \theta)$. Given $\lambda' = 6.55$ pm and $\theta = 50^\circ$, we calculate $\Delta \lambda$ and find $\lambda$. The correct incident wavelength is 5.68 pm.
