Art with polarisation
The ruler of Zane keeps breaking in the same place. Is there a device that can predict where the ruler will break?
Make a work of art with adhesive tape. If you place it between 2 polarizers, the artwork changes colors. You can also determine stress in plastic materials based on this principle.

- You can compare a polarizer with a grid.
- It absorbs waves with a polarization direction perpendicular to the transmission direction.
- Optically active materials can rotate the polarization direction of light.
- An LCD screen uses polarizers. It is the liquid crystals that twist the polarization direction of light.
- With polarizers you can also detect stress in plastic materials.
WHAT DO THE PARTICIPANTS LEARN:
Facts:
- Describe polarization of light via polarizers and after reflection.
- Describe the phenomenon of polarization of light by means of a model presentation.
- Describe the phenomenon of polarization after reflection and how this is prevented and used in practice.
- The basic physical concepts related to use polarization in an insightful way when conducting student tests, when describing technical designs and when making applications.
- Describe the function of polarizing filters using a concrete example.
Skills:
- Assembling
- Cooperation
- Art
- Building their own setup and linking observations to the theory.
