摘要
对于频率为几十赫兹的液体表面波,在反射光区域观察看到了清晰、稳定的干涉图样,给出了反射光强度包络的表达式,由此可以确定表面波的波形及各参数关系。进一步得到表面波动态表面张力、波速随频率变化关系图及波速随波长的变化关系图。
High visibility stationary interference fringes in the reflection field were experimentally observed for liquid surface acoustic wave at the frequoncies of a few tens Hertz.Reflected light intensity envelope expression is achieved,from this may determine the SAW shape and corresponding wave parameter.Further, the relations chart of surface tension, velocity and frequency have obtained.
