Principle

After it has been demonstrated in lessons that light undergoes interference, which can only be explained in the framework of classical physics by postulating a wave character for light, the question is now investigated of whether these are transverse or longitudinal waves.
 
This experiment is easy to perform and takes little time; it shows that light waves must be transverse waves.

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

Send a light beam through two polarising filters and investigate what happens when they are rotated against each other.
