Interference and Diffraction of Light

The distances between the central maximum and the diffraction minima for a single slit are measured by scanning the laser pattern with a light sensor and plotting light intensity versus distance. Also, the distance between interference maxima for two or more slits is measured. These measurements are compared to theoretical values. Differences and similarities between interference and diffraction patterns are examined.

Featured Equipment

Universal 550 Physics Experiment Bundle

This system provides a complete set of labs for mechanics, heat, light, sound, and electromagnetism.

550 Universal Interface

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.

PASPORT High Sensitivity Light Sensor

Designed to perform visible light studies from low intensity spectral studies to daylight. Built in oversampling reduces noise. PASPORT version.

PASPORT Rotary Motion Sensor

The PASPORT Rotary Motion Sensor measures angle, angular velocity, angular acceleration and linear position, velocity, and acceleration.

Precision Diffraction Slits

Includes two slit wheels allowing students to examine various diffraction patterns.

Support

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.
