Is faster than light communication possible??

Using a pole which is 1 light year long and with a person at each end of the pole who is able to push the pole so that it hits against a plate on the opposing end. Would it be possible for them to communicate using morse code and would the message be transmitted faster than the speed of light ??

I know the pole doesnt necessarily need to be that long but its a good example.

The far end of the pole would not move for many years, as the impulse imparted by pushing the near end would move at the speed of sound down the pole. In the case of a steel pole, the speed of sound is approximately 4,500 metres per second.

Surely if the pole was a solid all the way through when one and was moved the other end would move simultaneously and accordingly. However, as humans are not able to move fatser than the speed of light then the actual communication would be as though they were on the opposite side of a wall
