Quinke’s Interference Tube

A simple acoustic experiment for demonstrating how two sounds can cancel each other out when added together. Two Y-shaped glass tubes are connected by two rubber tubes of different lengths. A struck tuning fork is held at the end of one tube, and th... More.

3" Dia. x 4-ft. Metal Slinky Spring

The 4 ft. Slinky Spring with three times the normal length is ideal for demonstrating several fundamentals of wave motion. When the spring is extended to 30 feet, a lateral or longitudinal pulse can be observed in detail as it travels at the slower rate... More.

6-ft. Metal Helical Spring

Longer and heavier, the spring demonstrates the effects of greater mass and of greater tension. More.

Wave Demonstrator Set

The 4 ft. slinky spring with three times the normal length is ideal for demonstrating several fundamentals of wave motion. When the spring is extended to 30 feet, a lateral or longitudinal pulse can be observed in detail as it travels at the slower rate... More.
