    "abstract": "We present a simple thought experiment in which a beam of light of a finite\nlength (a light-pulse) enters a detection device that consists of a wave\ndetector and a light bulb. We examine the experiment from the reference frame\nwhere the device is stationary and from the reference frame where it moves at a\nconstant velocity along the axis of the beam. We use basic special relativity\nto derive the formulas that show how the length of the light beam is\ntransformed between the reference frames. We further show that the uncommon\nformulas for length transformation of a light beam do not contradict the usual\nrelativistic result that a uniformly moving non-light object will be Lorentz\ncontracted along the direction of its motion.",
