You still get a reflection in the heavy rope.  In the limiting case, 
with a zero mass per unit length rope in the small rope, it all 
reflects.  This is the equivalent of a open transmission line.  You 
can simulate this by tying a rope to a free sliding ring on a pole 
and launching a vertical wave down the rope.
