Experiment set OPTICS 3 plus


Wave optics experiments in daylight

The OPTICS 3 plus experiment set includes all the apparatus from OPTICS 3, but also has all the equipment needed for experiments on wave optics. Apart from the double-slit experiment, all the experiments can comfortably be performed without darkening the room. The experiment lamp from the OPTICS 1 set can be used as a bright light source. Once it is snapped into place on the standardised stand rod, it is inherently adjusted to the correct height for all the experiments.

Spectra from prisms and diffraction gratings

First, a hollow prism filled with water enables a very clear spectrum to be generated. If the red line is blocked off and sugar is stirred into the water, it is possible to investigate how the refractive index of the prism depends on the concentration of sugar. Then the spectrum produced by the prism can be compared with one generated by a diffraction grating. Another impressive experiment is to create a rainbow with the help of the raindrop model filled with water.

Precise measurements

The frames for the lenses and the concave mirror have the principal planes for the lenses or the tangent to the centre point of the mirror marked on them with dotted lines. This means all the distances can be easily measured to an accuracy of half a millimetre.
