The difference isn't the height it is the trajectory and ball speed. It will go a similar height but a 3 iron will maintain velocity on a high plane for a longer time while a 9 iron will reach peak height quickly and come down sooner (due to a loss of efficiency in energy transfer because of the greater angle of the face of the club). Throw a ball straight up at x speed and it will reach a certain height and come straight down in the same spot as it was launched. Throw the ball out towards the horizon at a slightly greater speed (accounting for energy loss) and it will reach a similar height but come down much further away of course and take a bit longer to reach the ground. Plain physics. Of course golf shots don't all take place in a vacuum and there are dozens of variables that contribute to the height and speed of a struck ball.
