Polarisation by filters

Principle

During the investigations an interference the students should have understood that certain optical phenomena can only be explained by the fact that Iight has wave properties. Now we must investigate the nature of these Iight waves, i.e., whether they are longitudinal or transverse.
This experiment is suitable as an introduction to polarization and is not time-consuming. Set-up and performance do not pose any problems.

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

Direct a beam of light through two polarization filters and investigate what happens when these are rotated at right angles to each other.
