Art with polarisation

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.

Toolkit

  • 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.
