Wave generated on the liquid column surface is an important origin of the liquid column disintegration. Hence, the wave characteristics on the liquid column injected into an air flow were experimentally and theoretically investigated. Critical wavelength, drop diameter and wave velocity were measured from the images for the varicose mode by high-speed video camera with a speed of 18000 frames per second. For the low relative velocity, good agreements are obtained between the Rayleigh's theoretical critical wavelength and the experimental values. On the other hand, for the high relative velocity, the critical wavelength is decreased with the increase in relative velocity. Therefore, the drop diameter is decreased with the increase in relative velocity for high relative velocity.
