An X-ray scattering experiment is performed on a crystal whose atoms form planes separated by 0.440 nm. Using an X-ray source of wavelength 0.548 nm, what is the angle (with respect to the planes in question) at which the experimenter needs to illuminate the crystal in order to observe a first-order maximum?

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...
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...
