	Optical Slits Apparatus A good tactile introduction to the wavelength of light, this is a self-contained exercise in diffraction and interference. Light source is provided along with red and blue filters and materials to make 10 sets of optical slits by hand.
	Resonant Circuits Apparatus A simple transmitter and receiver are used to study electromagnetic waves, RLC oscillators, diode rectification, directional antennas, and many other topics.
	Resonance Box with Tuning Fork Amplify the sound of a tuning fork using this wooden box with a tuning fork attached. Great for sound wave study.
	Digital Stroboscope An accurate digital readout combined with a well-engineered stroboscope makes this model and excellent value for industrial, school and laboratory applications.
	Resonance Tube Set - Open-Ended An alternative to using a tubes with water columns, this device allows you to find the wavelength of a tuning fork using two telescoping tubes. Includes a stopper for harmonics experiments and a striking pad for bench top use.
	Tuning Fork Sets Choose from 8-fork or 13-fork sets. Includes mallet and wooden box.
	General Purpose Stroboscope General purpose instrument can be used for all applications that do not require flash rate measurement.
	Buzzer In Vacuum Apparatus Sound cannot travel through a vacuum. Demonstrate this with the classic "bell in jar" experiment. The bell gets fainter as air is pumped from the jar and pressure decreases.
	Xylopipes Study the relationship between length and pitch. Includes twenty steel tubes with rubber rings at the vibrational nodes and a mallet with both a soft rubber and hard wooden end.
	Wave Motion Apparatus The inertia of the massive rods makes for slow and majestic displays of torsional waves that appear as transverse waves when viewing the colorful ends of the rods. Easily demonstrate and explain wave fundamentals.
	Stroboscope Discs This set of ten discs will give a variety of interesting optical illusions when rotated in the flashing light of a stroboscope.
	Sound Spectrum Chart Visually presents easy-to-understand ingredients of sound, including pitch, tone, pressure and vibration.
