photo finish | in general, any very close finish, in particular, a finish of a race in which the contestants are so close together that the winner must be determined from a photograph taken at the instant of finishing |
tidal flow tidal current | the water current caused by the tides |
riptide rip current | a strong surface current flowing outwards from a shore |
current stream | a steady flow of a fluid (usually from natural causes), the raft floated downstream on the current, he felt a stream of air, the hose ejected a stream of water |
photo opportunity photo op | an occasion that lends itself to (or is deliberately arranged for) taking photographs that provide favorable publicity for those who are photographed |
stream flow current | dominant course (suggestive of running water) of successive events or ideas, two streams of development run through American history, stream of consciousness, the flow of thought, the current of history |

Peruvian current Humboldt current | a cold ocean current that flows north along the Pacific Coast of South America before turning west |
dynamic electricity current electricity | a flow of electric charge |
thermionic current | an electric current produced between two electrodes as a result of electrons emitted by thermionic emission |
ultraviolet ultraviolet radiation ultraviolet light ultraviolet illumination UV | radiation lying in the ultraviolet range, wave lengths shorter than light but longer than X rays |
wind air current current of air | air moving (sometimes with considerable force) from an area of high pressure to an area of low pressure, trees bent under the fierce winds, when there is no wind, row, the radioactivity was being swept upwards by the air current and out into the atmosphere |
red currant garden current Ribes rubrum | cultivated European current bearing small edible red berries |
