Unformatted text preview: 66. For x-ray (“Bragg”) scattering, we have 2d sin θm = m λ. This leads to 2d sin θ2 2λ = 2d sin θ1 1λ ⇒ sin θ2 = 2 sin θ1 . Thus, with θ1= 3.4°, this yields θ2 = 6.8°. The fact that θ2 is very nearly twice the value of θ1 is due to the small angles involved (when angles are small, sin θ2 / sin θ1 = θ2/θ1). ...
