... 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 roundtrip times differ by an amount (l)(v2/c3). Now, 2l/c is just the time the light would take if there were ...

Time in physics
Time in physics is defined by its measurement: time is what a clock reads. In classical, non-relativistic physics it is a scalar quantity and, like length, mass, and charge, is usually described as a fundamental quantity. Time can be combined mathematically with other physical quantities to derive other concepts such as motion, kinetic energy and time-dependent fields. Timekeeping is a complex of technological and scientific issues, and part of the foundation of recordkeeping.
