See Einstein experiment with innovations: light pulse is longer (moves by its side relatively), and with interferential picture:

To prove that this embodiment of the SQR expression refers not to the relative time but to relative speed, here you are, "the table data of different time delays of beams between the vertical parallel mirrors". [img]http://www.relativity.hotmail.ru/Table(eng).png[/img]
Beams between vertical parallel mirrors can have from one to milliards and more touches to the opposite mirrors, and their lengths difine their delay times between the mirrors. Division of the mirror's length into different delay times, gives different relative speeds.- Interferential pictures appearing between the falling and the reflected beams define different delay times, beam lengths and speeds. !!!!!
The last column in the table is delay time, put forward by A.Einstein - about 0 second. In all cases it is 0 second: A.Einstein wants no interferential pictures here at all, no differences in the touches, as if there were no touches to the opposite mirror at all, and none of the delays. This assertion of Einstein can be checked: millards touches beam should have 4 seconds of delay time, that is 4 seconds of photosensitive device activity.
The interferential pictures of the new animation

easily shows the abovesaid about vertical mirrors. Vertical interferential picture corresponds to the relative light speed and horizontal picture - to the speed of the mirrors.
Light pulse moving up and down by its side has relative speed. This means you apply your own speed to look the other side of the moving object.
