Paper Abstract

The article provides a description of the hypersonic acoustic wave frequency measurements in the piezoelectric LiTaO3 crystal. Especially it contains the description of an experiment preparation. The main purpose was an observation of the acoustic waves in the same crystallographic direction, however for different frequencies of the acoustic waves, to find dispersion relations for the wave velocities. Before the measurements calculations of the frequencies were performed. For the calculation ultrasonic data were used. A comparison with current hypersonic results shows a difference in the values of the acoustic wave frequency. The c66 elastic constant of the LiTaO3 was also examined in the range of frequencies equal to 20.4 GHz-29.4 GHz.
