Dispersion of ultrasonic velocity in liquids
Three ranges of frequencies from about 1·5 mc. to 7 mc. were employed in five liquids: xylol, benzene, carbon tetrachloride, carbon disulphide and water. In the case of distilled water an additional frequency 22·5 mc. was also used. It is concluded from the data obtained for these liquids that within the limits of experimental error there is no definite evidence of acoustic dispersion over the frequency range employed.
