摘要: 将水的表面波视作一种正弦相位型光栅,导出了水表面波衍射光斑间距与其波长的关系,从而利用水表面波对激光的衍射测定了水波波长,确定了表面波成分,即在所用实验频率范围内毛细波占主导地位,验证了表面波的色散关系.

关键词: 水波, 表面波, 相位型光栅, 毛细波, 色散关系

Abstract: The surface wave of water is regarded as a grating of sine phase type and the laser diffraction pattern thereby is related to the wavelength thereof. It turns out that the composition of the surface wave is mainly the capillary wave, at last the dispersion relation of this wave is verified.

Key words: water surface waves, phase grating, capillary waves, dispersin relation
