How are swimming races timed?

Answer 1

Pressure sensors are used to determine times. In addition, video cameras recording at 2,000 frames per second are used to accurately determine winners in the event of a very close "photo finish"

Answer 2

The swimmers get into the start position and then there is a loud beep when the clock starts, this signals the swimmers to dive in. Once the swimmers have swum the correct number of laps they hit the wall which has a pad on it which will stop the clock for your lane and tell you how fast you swam.

Answer 3

Swimming i judged by who touches the wall first at the end of whatever distance the swimmers are supposed to swim. swimming is also timed by officials and a pressure sensing pad on the wall.

I hope this helps.

Answer 4

There is a tiny switch attached to the trigger of the starting pistol. It starts the clock as soon as it detect the trigger has been pulled. The clock runs until one of the competitors breaks an electronic beam at the finish line.

Answer 5

yes, The black squares on each end of the pool has a sensor that tracks time to 1/100th of a second. Also tracks that they didnt turn early when turning back the other way.
