For carrying out this experiment the room should be rather dark,
particularly for the part where the spectrum is viewed through the
grating. It is important not to look directly from the front into
the light cone. If you have a problem seeing a colour there is the
further option of slightly increasing the distance between the
fluorescent screen and the tube and viewing the colour of the light
spot on the screen. In this case only that part is reflected which
does not contribute to the fluorescence.
Bei diesem Versuch wird die Anzahl der absorbierenden Schichten
(Graufilter) verändert und die Lichtintensität gemessen. Als
Ergebnis erarbeiten Sie in diesem Experiment eine Formel für die
Abnahme der Intensität in Abhängigkeit der Schichtdicke, durch die
das Licht geht. Anmerkung: Die Variation der Anzahl der Graufilter
kann als Änderung der Dicke eines einzelnen Körpers aufgefasst
werden.
