Unformatted text preview: . Imagine a measuring rod at rest in the moving frame S , where its proper length is L . An observer, stationary in S , calculates the length of the rod using the time interval between the passing of the two end of the rod at his origin O in S . From this he measures L = u t (19) in the stationary frame S . The observer in S , notices the passing of the two end of the rod at the origin to happen at L = L = u t (20) 3 Thus L L = L L = t t (21) But, from our result of time dilation, t t = 1 1-( u/c ) 2 (22) therefore L = t t L = 1-( u/c ) 2 L (23) therefore, the length of the rod is shorter when measured in a frame moving with respect to its stationary frame, with proper length L . 4...
