Experiment set OPTICS 3

Hollow prism and raindrop model
The OPTICS 3 experiment set, like its sister set OPTICS 2, includes equipment for image and shadow forming, but also allows for additional experiments on prism spectra and rainbows. 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.
A hollow prism filled with water enables a fabulous 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. Another impressive experiment is to create a rainbow with the help of the raindrop model filled with water.
The universal track is also used as an optical bench
The same profiled rail used as a track, a stand, an inclined plane and a sliding surface for friction experiments in the MECHANICS sets is used here as an optical bench. The start of the scale is about 15 cm in from the end of the rail so that that object to be imaged (slide) can be positioned directly over the zero mark. This makes for extra-easy measurement of object and image distances. The universal track is not included in the set.
Enhancement with wave optics
The OPTICS 3 experiment set can also be enhanced easily by the OPTICS 3 plus set. All that needs to be done is to remove the cover exposing the storage slits which accommodate the diffraction and polarisation components.
