... This means v2/c2 is a small number so we approximate the roundtrip time to go upstream and downstream to be (2 l / c)(1+v2/c2). From Pythagoras’ theorem, the cross-stream speed is √ (c2-v2). The roundtrip cross stream time will be 2l / √ (c2-v2). This can be approximated as (2l/c)(1+v2/2c2). The two ...
