An x-ray beam of wavelength λ1 is incident on a crystal at an angle α1 = 40.0° with respect to the surface and undergoes first-order reflection from a set of Bragg planes. A second x-ray beam of wavelength λ2 = 80.0 pm is incident on the crystal at an angle α2 = 60.0° with respect to the surface, and undergoes second-order reflection from the same set of Bragg planes. The set of Bragg planes of interest make an angle of...
X-rays of wavelength 0.0983nm are directed at an unknown crystal. The second diffraction maximum is recorded when the X-rays are directed at an angle of 23.7 degrees relative to the crystal surface. What is the spacing between crystal planes?
#2 and 3 Perhaps to confuse a predator, some tropical beetles are collared by optical interference that is due to scales whose alignment forms a diffraction grating (which scatters light instead of transmitting it). When the incident light rays are perpendicular to the grating, the angle between the first-order maxima (on opposite sides of the zeros-order maximum) is 31degree in light with a wavelength of 550 nm. What is the grating spacing of the beetle? What is the smallest Bragg...
Problem 2: X-ray diffraction: (a) Determine the maximum wavelength for which constructive interference can be observed in the Bragg model for a simple cubic crystal with a lattice constant of 3.6 A. (b)What is the energy of the X-rays in electron volts? (c) If you were to perform neutron diffraction, what would the energy of the neutrons have to be in order to obtain the same de Broglie wavelength? (d) You could argue that if you take X-rays with twice...
X-rays with a wavelength of 1.34 Å scatter at an angle of 29.0 ∘ from a crystal. If n=1, what is the distance between planes of atoms in the crystal that give rise to this scattering?
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 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...
