question 75

Multiple Choice

The figure shows X-rays incident on a crystal spectrometer that are reflected from the crystal and used for Compton scattering in a carbon block. Of the wavelengths shown, $\lambda$ ₃ $\neq$ $\lambda$ ; thus, which of the following expressions is true?

• A) \(\lambda\)₁ =\(\lambda\)₂ = \(\lambda\)₃ = \(\lambda\)₄
• B)\(\lambda\) = \(\lambda\)₁ > \(\lambda\)₃
• C) \(\lambda\)< \(\lambda\)₂ < \(\lambda\)₁ < \(\lambda\)₄
• D) \(\lambda\)₃ > \(\lambda\)₁ = \(\lambda\)₄
• E) \(\lambda\)₄ > \(\lambda\)₂ > \(\lambda\)
