I thought it became somewhat clear that the rocking motion that your finger exercise was supposed to show was indeed erroneous. Askenfelt clearly addressed thot point and said the rocking motion the bridge experiences was caused by longitudinal waves. For that matter I have yet to see anyone from either camp address the frequency dependent speed of sound issue that results from the particular kinds of complex transverse waves that he says occurs. Being more curious about all this then worried about who's right or wrong I would really like to hear some concrete discussion about these things as they do seem to conflict somewhat with the way the bridge motion model was earlier described. -- Richard Brekne RPT, N.P.T.F.
