Altitude measurement on a trail

Principle

The altitude profile of a hiking trail or route to school can be measured during a school trip or as an exercise for the students. The altitude profile can also be used to demonstrate that the atmospheric pressure decreases when the altitude increases. As a result, the experiment is ...

Examination of the structure of NaCl monocrystals with different orientations

Principle

The spectra of the X-rays that are reflected with various different orientations by NaCl monocrystals are analysed. The associated interplanar spacings are determined based on the Bragg angles of the characteristic lines.

Tasks

  1. Determine the intensity of the X-rays that ...

X-ray investigation of cubic crystal structures / Debye-Scherrer powder method

Principle

When polycrystalline samples are irradiated with X-rays a characteristic diffraction pattern results. These Debye-Scherrer reflections are photographed and then evaluated.

Tasks

  1. Debye-Scherrer photographs are to be taken of powdered samples of sodium chloride and caesium ...

X-ray investigation of hexagonal crystal structures / De

Principle

A polycrystalline zirconium foil is irradiated with X-rays. The resulting Debye-Scherrer reflections are photographed and then evaluated.

Tasks

  1. Take Debye-Scherrer photographs of the zirconium sample.
  2. Evaluate the Debye-Scherrer rings and assign them to ...

Debye-Scherrer diffraction patterns of powder samples with three cubic Bravais lattices

Principle

Polycrystalline powder samples, which crystallize in the three cubic Bravais types, simple, face-centered and body-centered, are irradiated with the radiation from a Roentgen tube with a copper anode. A swivelling Geiger-Mueller counter tube detects the radiation that is ...
