A monochromatic X-ray beam with the wavelength 1.585 A is incident on an Aluminium crystal and is parallel to the (010) planes. When the incident beam makes and angle of 11.31° with the [100] direction, there is a diffracted beam that is also parallel to the (010) planes. Give the indices of this reflex, i.e. which set of planes are giving rise to the diffraction?

At room temperature, the diffractogram of a cubic material with lattice parameter of 10Å presents a peak at 2θ = 20o. At a higher temperature, the lattice parameter has expanded 20%. Calculate the 2q value of the diffraction peak of the material at the high temperature. λλ is fixed. Do not assume a particular (hkl) set of values, nor a value for λ.

All X-ray diffraction structures correspond to their solution structure? True or false. Why?

The wavelength of characteristic x-rays in the K, line from a particular source is 0.152 nm. Determine the material in the target.
