Abstract
The objective of this research was to construct an experimental set to determine the sound speed in solids by resonance of the sound wave. In this experiment was to find the sound speed in four kinds of material rods; such as brass, copper, iron and aluminum. The percentage error values of the sound speed in solids were calculated and were compared to the standard value of sound speed in each of solids. The result investigated that the sound speed values in brass, copper, iron and aluminum were 3484.00, 3635.48, 4910.11 and 4914.35 m/s; respectively. The percentage error values of sound speed in brass, copper, iron and aluminum were 0.46%, 1.74%, 2.77% and 4.58% respectively.
