Length contraction 2

  1. Apr 1, 2009 #1
    I understand the explanation for time dilation involving the light clock on the spaceship, or a train. But what is used to explain length contraction. Is there another example that is used involving a light beam and a spaceship.

    The first situation used a light clock oriented transverse (perpendicular) to the direction of relative motion to reveal time dilation.

    Now, use a light clock oriented longitudinally (parallel) to the direction of relative motion... and require that one tick of this clock has the same duration as that of the first clock.

    Look at my avatar.

    Thanks robphy. I think I understand it now.

    Well if you understand time dilation you are doing well, very well, indeed. I came across this recently and while I believe it's correct, it sure is interesting.....anybody like to explain it???
