Polarisation by reflection

Principle

As a result of the experiment the students should realize that Iight reflected from plexiglass and glass is partly polarized, and that the degree of polarization depends upon the angle of incidence. They should also know that reflection from metal surfaces does not bring about polarization; to demonstrate this, metal plates with smooth surfaces, i.e. with good reflection properties, will be utilized.

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

Using various materials, investigate whether Iight which has been reflected from their surfaces is polarized and if so, whether the polarization is dependent on the angle of reflection.
