However, due to the camera's frame rate, the same positions are occupied each time you check back, thanks to the action of the periodic sine wave and the uniformity of the water flow (the water droplets are identical). read more
Sound wave are longitudinal wave,they move by compression and rarefraction. Because of these compression of sound wave pushes the water. So it alter the flow of water. read more
The change in speed changes the direction of the waves, making it hard to determine where the sound originally came from. Sound and Salinity Salinity can also be a factor in determining the behavior of sound. read more
