ACOUSTICS

Chladni figures-making sound visible   The Chladni figures are named after the German scientist Ernst Florens Friedrich Chladni (1756-1827). Chladni excited the normal modes of thin metal plates covered with sand by stroking ... more

Sound waves propagate longitudinally in gases. The group velocity here is equal to the phase velocity. In this experiment, we will measure the propagation time of a sound pulse between two microphone probes in Kundt’s tube ... more

Sound waves propagate in gases in the form of longitudinal waves. The overall velocity is equivalent to the phase velocity. In this experiment a standing wave is generated inside Kundt’s tube with both ends closed off. The ... more

The equipment set consists of test rods of various lengths, made of different materials, two microphone probes, a microphone box for recording and amplifying signals and outputting them to an oscilloscope along with three mats. ... more
