Rotation of the polarisation plane with a sugar solution

Principle

This experiment makes great demands on the students. The saccharimeter model must not only be meticulously constructed, but the measurements also require painstaking care. This is made even more difficult by the requirement for complete darkness in the physics laboratory.
The obvious solution is a division of labour. For example, the class can be divided into two groups, which perform the measurements with the single or double layer thickness, respectively. Subsequently, the results can be exchanged and recorded.

Benefits

• Multifunctional light box - All-in-one: Can be used for geometric optics on the table, colour mixing and on an optical bench
• Extension with others sets at anytime, no additional light sources needed, recognition value for students

Tasks

How does a saccharimeter work? To construct a model of a saccharimeter and investigate how a sugar solution behaves when polarised light is passed through it.
