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?

When X-rays with ž. - 1.937 A are used, the second-order Bragg reflection from a set of parallel planes in a(n) potassium crystal is observed at an angle 0-21.32°. If the spacing between these planes corresponds to the unit cell length (d-a), calculate the edge length of the potassium unit cell. Submit Answer Retry Entire Group 9 more...
The metal potassium crystallizes in a body centered cubic unit cell with one atom per lattice point. When X-rays with λ = 1.937 Å are used, the second-order Bragg reflection from a set of parallel planes in a(n) potassium crystal is observed at an angle θ = 21.32°. If the spacing between these planes corresponds to the unit cell length (d = a), calculate the radius of a(n) potassium atom.
The metal iron crystallizes in a body centered cubic unit cell with one atom per lattice point. When X-rays with λ = 0.7107 Å are used, the second-order Bragg reflection from a set of parallel planes in a(n) iron crystal is observed at an angle θ = 14.35°. If the spacing between these planes corresponds to the unit cell length (d = a), calculate the radius of a(n) iron atom. _________Å
When an x-ray beam is scattered off the planes of a crystal, the scattered beam creates an interference pattern. This phenomenon is called Bragg scattering. For an observer to measure an interference maximum, two conditions have to be satisfied: a). An x-ray beam with wavelength 0.120 nm is directed at a crystal. As the angle of incidence increases, you observe the first strong interference maximum at an angle 23.0 ∘. What is the spacing d between the planes of the...
