摘要:
An optical method for the quantitative study of ultrasonic wave fields at frequencies below 1 Mc/sec has been developed and applied to stationary waves. The method is based on the effect of mirage. A detailed theoretical analysis shows the possibility of determining wave forms and sound pressure amplitudes. Some experimental results of sound velocity and pressure amplitude determinations are given. The records of wave forms in several liquids indicate the distortion of waves during propagation.
