Abstract:We explored the experiment of ‘acousto-optic diffraction and Measurement of Velocity of Sound in liquid’ ,and an experimental device for measuring the diffraction spot center was designed and assembled. The device reduces the error which was caused by the traditional experimental method in measurement of the spot distance,the improved measurement method is simple,and the results are accurate.
Keywords:acousto-optic diffraction  error analysis  experiment improvements
