| Abstract: | The relation between air bubbles density and the depth from surface of water,the wind speed at water surface is introduced in this paper.Motions of bubbles of small,intermediate and large size are also stated too.The light scattering property of bubbles is discussed and a simple method to calculate the optical property of air bubbles is clarified.In this paper,problems related to the optical methods to study air bubbles are stated.Analyses of high speed photography of bubbles show that bubbles'speed is consistent with the results of theoretical calculation.All these show that detecting wakes of bubbles and tracing targets optically are feasible. |

| Keywords: | air bubble bubble density terminal velocity optical properties high speed photography |
