Principle
In order to be able to set up in such a way that all the slides
fit between the light sensor and the LED without having to shift
the mounts, the 5 slides are first held between the light sensor
and the tube on the LED and the mounts are pushed together
accordingly.
Benefits
- Specified for the requirements of the german final secondary-school examinations
- Especially for secondary schools
- Quantum and wave optics in a student experiment
Tasks
How id light attenuated when passing through substances? When
light passes trough a substance or liquid the intensity is
attenuated. This attenuation can be demonstrated by means of a
light sensor. In this experiment the number of absorbing layers
(grey filters) is modified and the light intensity is measured.
Eventually you will develop a formula in this experiment for the
reduction in intensity as a function of the thickness of the layer
that the light passes through. Note: The variation in the number of
grey filters can be interpreted as a variation in the thickness of
a single body.
