Abstract
When DC electric field is applied perpendicularly to silicone oil-water interface, the interface becomes unstable and conic waves are generated. This type of wave is called Taylor cone, and there are features in conical shape and the angle of vertex of the cone. The conic wave, generated in the mesh of a metal net set up on the interface, is taken of a picture with the high-speed video camera, and analyzed on the monitor. As a result, change of the height of conic wave and the angle with time is clarified.
