摘要: A stably density-stratified liquid is produced in a rectangular glass tank by variation of the concentration salt water as function height. The placed into parallel beam schlieren interferometer with Wollaston prism adjusted to produce straight vertical fringes. gravity wave cross type excited and resulting periodically deforming fringes are recorded taking photographs. method developed obtain from fringe patterns results about propagation space time amplitude attenuation. compared linear theory Thomas Stevenson (1972) excellent agreement found within limits approach.
