The formula for length contraction gives the length of an interval on a ruler moving with velocity v relative to an observer as L' = L 1 - where L is the length of the same interval on a ruler at rest with respect to the observer. By what fraction is the length of a meter stick reduced if its velocity relative to you is measured to be 67 percent of the speed of light? L- L'
