Experiment Topics:
· Speed of propagation of sound pulses in various rods
· Comparison between the propagation of longitudinal and transverse waves
· Standing sound waves in short rods
· Polarity of reflections at the ends of the rods
· Multiple reflection at the ends of longer rods
Benefits:
· Compact set-up on lab benches
· Non-contact and low-attenuation measurement of sound waves
Equipment set for investigating propagation of sound and determining the speed of sound in solid rods of various materials. The set includes various test rods, two microphone probes and a microphone box for connection to an oscilloscope. Contained in a rugged plastic case with foam inlays in the shape of the apparatus and a transparent lid.
