QUESTION:

Measuring the Speed of Light: Michelson In 1926, Albert Michelson measured the speed of light with a technique similar to that used by Fizeau. Michelson used an eight-sided mirror rotating at \(528 \mathrm{rev} / \mathrm{s}\) in place of the toothed wheel, as illustrated in Figure 25–25. The distance from the rotating mirror to a distant reflector was \(35.5 \mathrm{~km}\). If the light completed the \(71.0-\mathrm{km}\) round trip in the time it took the mirror to complete one-eighth of a revolution, what is the speed of light?
