Time interval with three phones
Time interval with three phones

If phone one takes a photo (with flash) of phones two and three while both measure light you should get two stopwatches starting at the same time.

See gif below (sorry for quality and that only one phone is triggered in the gif).
Is there a simple way of assessing how accurate such a measurement can be?

(for example, as in the gif, when measuring the speed of a passing LED-light mounted on a toy car)

Best regards.
