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.
