Description

Frey Scientific Buzzer in a Vacuum is a updated version of the bell in a jar unit and helps in demonstrating that sound waves do not propagate in a vacuum. It requires 0.25 in tubing. 9.5 in Unit with 8 in dia has buzzer leads that are connected to a dry cell and the air nipple to any laboratory vacuum pump. Since air is evacuated from the jar, the sound of the steady buzzer diminishes in intensity.
