Wakes behind cylinders and plates were photographically investigated at Reynolds numbers from 0.1 to 2,000. Main results are as follows. In the case of a circular cylinder, the rear twin-vortices begin to form At R=5(R is Ud/ν), then become more and more enlarged as R increases, and finally become asymmetrical at about R=45. The laminar wake, on the other hand, begins to oscillate sinusoidally some distance downstream at R=30. In the case of a flat plate parallel to the flow, the wake begins to oscillate sinusoidally some distance downstream at about R=700(R is Uι /ν, where ι is the length of the plate). Lastly, some detailed knowledges about the structure and the nature of the Karman vortex street are obtained by a new method.
