POLARISATION

Objective: Verify Malus’ law for linearly polarised light. Malus’ law describes how intensity I of polarised light with an initial intensity I0, having passed through an analyser filter, depends on the angle of rotation of the ... more

Objective: Investigate the rotation of the plane of polarisation by sugar solutions Sugar solutions are optically active, in other words they rotate the plane of polarisation of any linearly polarised light that is passed through them. The ... more

Objective: Demonstration of Pockels effect in a conoscopic beam path The Pockels effect is an electro-optical effect in which an electric field within a suitable material splits a light beam into two beams polarised perpendicular to one ... more

Objective: Demonstrate the Faraday effect and determine the Verdet constant for flint glass Optically isotropic, transparent, non-magnetic materials become optically active in a magnetic field. They rotate the plane of polarisation of linearly ... more
