The volume expansion of liquids and the linear expansion
of various materials is determined as a function of
Se determina la dilatación lineal de varios materiales en
función de la temperatura.
With the aid of two mirrors in a Michelson arrangement, light is
brought to interference. Due to the magnetostrictive effect, one of
the mirrors is shifted by variation in the magnetic field applied
to a sample and the change in the interference pattern
Approaching a very sharp metal tip to an electrically conductive
sample by applying a electrical field leads to a current between
tip and sample without any mechanical contact. This so-called
tunneling current is used to investigate the electronic topography
on the sub nanometer ...
Aproximando una punta aguda de silicona montada en un voladizo
(cantilever) para tomar una muestra de una superficie se produce
una interacción a escala atómica. El resultado es que el
voladizo se curva, lo cual se detecta con láser. En modo ...
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.
When polycrystalline samples are irradiated with X-rays a
characteristic diffraction pattern results. These Debye-Scherrer
reflections are photographed and then evaluated.
A polycrystalline zirconium foil is irradiated with X-rays. The
resulting Debye-Scherrer reflections are photographed and then
Laue diagrams are produced when monocrystals are irradiated with
polychromatic X-rays. This method is primarily used for the
determination of crystal symmetries and the orientation of
crystals. When a LiF monocrystal is irradiated with polychromatic
X-rays, a characteristic ...
This experiment provides training in determining the length and
position of an object based on an X-ray image. A metal pin that is
embedded in a wooden block is used as the model. This experiment is
also an excellent preparatory exercise for demonstrating the
principle of ...
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 ...
A polycrystalline powder sample of zinc is irradiated with the
radiation from a X-ray tube with a copper anode. A Geiger-Mueller
counter tube is automatically swivelled to detect the radiation
that is constructively reflected from the various lattice planes of
the crystallites. ...
