Sound propagation in rods 3D virtual laboratory work on physics (section: Mechanics).
INTENTION: Simulation of the laboratory work on general physics.
PURPOSE: Investigation of longitudinal sound waves in cylindrical rods and determination of propagation velocity of longitudinal sound waves.
SUMMARY: Sound waves in solids can propagate as longitudinal waves, transverse waves, compression-expansion waves or bending waves. Elastic longitudinal waves propagate along a rod through a periodic sequence of compression and extension along the length of the rod. If the diameter of the rod is small compared to its length, the speed of propagation depends only on the elastic modulus and density of the material. In this experiment, the speed is determined by the time it takes sound impulses to travel through the rod.
