A beam of electrons with kinetic energy 50 eV strikes the surface of a NaCI crystal. The spacing between the planes of the crystal is 0.281 nm. At what angle to the surface do we see a maximum in the reflected electron beam? (You can assume the electrons are nonrelativistic, and therefore K - p2/2m.) The same beam of electrons impinges on a pair of slits. A first-order diffration maximum is seen at 30 degrees to the incoming electron direction....

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...

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...

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?
