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.
