The Figure Shows X Rays Incident on a Crystal Spectrometer

question 137

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, λ₃ ≠ λ; thus, which of the following expressions is true?

• A) λ ₁ =λ ₂ = λ ₃ = λ ₄
• B) λ = λ ₁ > λ ₃
• C) λ < λ ₂ < λ ₁ < λ ₄
• D) λ ₃ > λ ₁ = λ ₄
• E) λ ₄ > λ ₂ > λ
