X-Ray Diffraction: a Researcher Is Investigating a Cubic Crystal with X-Rays

question 15

Short Answer

X-ray diffraction: A researcher is investigating a cubic crystal with X-rays. He is looking at Bragg reflection from the planes parallel to the cube faces. He finds that when using X-rays of 0.165 nm a strong first maximum occurs when the beam makes an angle of 23.5° with the planes. What is the spacing of adjacent atoms in the crystal?
