The Wireless Sound Sensor measures sound wave forms and sound level in one compact and portable sensor.

The Wireless Light and Color Sensor features an ambient and a directional RGB color light measurements.

Use a signal generator to drive this oscillator for wave and oscillation experiments.

Wireless Diffraction System - complete with Diffraction Scanner, Laser, Slits, and Optics Bench.

Demonstrate all manner of basic wave phenomena with this easy to use and complete system. Includes all necessary equipment.

Includes a Red Diode Laser and two slit wheels that allow students to examine various diffraction patterns.

Drives a string or elastic cord to produce a standing wave. Use it to study frequency, wavelength, and resonance. It’s well-suited for demos and hands-on experiments.

Sand sprinkled on the Chladni plate will gather on nodal lines when vibrated, dramatically revealing the intricate patterns

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

An LED strobe controller with modular lamps to illuminate any shape. Includes stroboscope controller and one lamp module.

The Sine Wave Generator generates, controls, and stores the very same sine wave signals used by speakers and wave drivers.

An all-in-one bright point source, illuminated crossed-arrow object, primary-color source, and ray box with up to five parallel rays.

A rotating disk with a polar grid that provides an excellent surface for measuring incident, reflected, and or refracted light rays.

Three independently controllable LEDs offer a simple way to explore light and color.

A complete optics bench that includes all the components required to do introductory optics experiments.

Attaches optical components directly to a Dynamic Tracks via carriages that can be positioned anywhere on the track.

Plastic lenses create images for normal vision, far-sightedness, near-sightedness and astigmatism. Additional lenses are placed in front of the eye to correct for vision problems.

With this two-string guitar, students can hear the resonance modes of the strings.

Allow mechanical waves to be created to demonstrate the behavior and properties common to many types of waves.

This thick glass bell jar with base plate includes an electric bell on a rubber mount to demonstrate that sound does not propagate in a vacuum.

Both rugged and economical aluminum tuning forks. Includes eight forks representing a full octave of frequencies.

Two nested cardboard tubes allow students to vary the length of a column of air and study resonance in both open and closed tubes.

The basic system is built around a Gunn Diode Transmitter and receiver, and is designed to aid students in understanding and visualizing electromagnetic wave interactions.
