Laser light is passed through two polarizers. As the second polarizer (the analyzer) is rotated by hand, the relative light intensity is recorded as a function of the angle between the axes of polarization of the two polarizers. The angle is obtained using a Rotary Motion Sensor that is coupled to the polarizer with a drive belt. The plot of light intensity versus angle can be fitted to the square of the cosine of the angle allowing us to verify the Law of Malus.PreviewDownload

This system provides a complete set of labs for mechanics, heat, light, sound, and electromagnetism.
The 550 is fast, powerful, and incredibly affordable. It offers half the ports and many of the same features as our 850 Interface in a smaller package.
Designed to perform visible light studies from low intensity spectral studies to daylight. Built in oversampling reduces noise. PASPORT version.
The PASPORT Rotary Motion Sensor measures position, velocity, and angular and linear acceleration.
Measures relationship between light intensity transmitted through set of polarizers and angle of the polarizers.
Many lab activities can be conducted with our Wireless, PASPORT, or even ScienceWorkshop sensors and equipment. For assistance with substituting compatible instruments, contact PASCO Technical Support. We're here to help.
