Table 1 10. 



VELOCITY OF SOUND IN SOLIDS. 



The numbers given in this table refer to the velocity of sound along a bar of the substance, and hence depend on the 

 Young's ^Iodulus of elasticity of the material. The elastic constants of most of the materials given in this table 

 varj- throuiih a somewhat wide range, and lience the numbers can only be taken as rough approximations to the 

 velocity which may be obtained in any particular case. When temperatures are not marked, between lo^ and 20°
