A long train is heading for an long tunnel. If the train moves sufficiently fast, is it possible, according to experimenters on the ground, for the entire train to be inside the tunnel at one instant of time? Explain.
Yes, due to length contraction.
We have given,
Length of the train =
Length of the tunnel =
We have to know is it possible that at some time the whole train will be inside the tunnel.
Since there are two events are given,
Event 1: One front of the Train at the entrance of the
Event 2: One front of the train at the exist of the tunnel
When the speed of the train will be comparing to speed of the light then it will be observed by the ground that it is whole inside the tunnel.
That will happens due to length of contraction of train.
