  1. 1. Standing Wave Yi Jia You
  2. 2. This kind of water basin was first made in the Tang dynasty (618 – 907 AD), which was an imperial dynasty of China. The special thing of this basin is that droning sound is created when people rub these two ears with wet hands, and the water inside will jet into the air. Ears http://www.youtube.com
  3. 3. WHY? The ears vibrate with a frequency as someone rubs them. As thisfrequency getting close or equal to the natural frequency of the body of basin, the droning sound is created. The vibration of basin generates waves that transmit by the water and standing waves are created when two waves interfere, constructive interference in this case, as shown on the figure above. The water that jets into the air is at the antinode, where the highest point of the wave is.
  4. 4. This basin is an application of standing wave and the principle of superposition.
