Wakes behind cylinders and plates were photographically investigated at Reynolds numbers from 0.1 to 2,000. Main results are as follows.<BR>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.<BR>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 Ul⁄ν, where l is the length of the plate).<BR>Lastly, some detailed knowledges about the structure and the nature of the Kármán vortex street are obtained by a new method.
