By 'absorved' i meant transformed (without reflecting
back).. the lighter rope would 'absorve' the wave if
the heavy rope didnt get anything back, even though
its generating a 'wider' wave. The wall receiving and
dissipating the impact along a wide surface..

I thought electricity was electrons going along the
wire, how come it acts like a wave?
