Klinger Malus' Law Experiment

Experimentally verify Malus' law.

• Optical bench makes precise optical alignment easy
• Analyzer may be rotated precisely within 1° without disturbing the optical alignment
• Sensitive digital lux meter enables precise measurement of light intensity (1 lux)

Light, when modeled as a wave phenomenon, can be classified as a transverse electromagnetic wave consisting of oscillating electric and magnetic fields that are oriented perpendicular to each other. Depending on the orientation of the plane of polarization of the electric field with respect to the direction of propagation of the wave, the wave can be classified as polarized or un-polarized. To measure the variation of transmission of an EM wave through two polarizers as a function of the angle of orientation between them and prove Malus's law.

Ordering information: Kit includes optical bench set 0.4 m, light source holder, polarizer holder, analyzer holder, light sensor holder, power supply for light source, data processor.
