The frequency f 1 depends upon the density and elasticity of the material from which the bars are made. The amplitudes for the f 2 and f 3 modes would actually be much smaller than the fundamental. These mode frequencies appear with a tuning fork since it can be considered to be two clamped bars. Free bar modes.
