Acoustic Mirror
| |
| This image shows a device called "Schallspiegel" [acoustic mirror] which was designed to demonstrate acoustic reflections. The experimental setting, as shown above, was part of a larger exposition in the late 19th century at the Urania in Berlin. This location played a decisive role in the beginning movement of the popularisation of science, which found its expression in a growing interest in experiment kits for the public as well. | |
