That's one possibility... Another is that the actual line is much narrower than what you see, but the frequency is varying about a mean so fast that it APPEARS to our measuring instruments as a wider, single line. -Mark Iverson -----Original Message----- From: mix...@bigpond.com [mailto:mix...@bigpond.com] Sent: Friday, June 21, 2013 10:36 PM To: vortex-l@eskimo.com Subject: Re: [Vo]:Mark has blazed the path In reply to David Roberson's message of Fri, 21 Jun 2013 13:52:29 -0400 (EDT): Hi, [snip] >It is not clear how a reduction in Q would reveal itself in this situation. What indications are there that the resonant frequencies might vary as stress is applied? I would expect there to be a direct correlation between the Q and the line width of spectral lines.
