Editing Standing wave (section)

=== Mechanical waves ===
Standing waves can be mechanically induced into a solid medium using resonance.  One easy to understand example is two people shaking either end of a jump rope.  If they shake in sync, the rope will form a regular pattern with nodes and antinodes and appear to be stationary, hence the name standing wave.  Similarly a cantilever beam can have a standing wave imposed on it by applying a base excitation. In this case the free end moves the greatest distance laterally compared to any location along the beam.  Such a device can be used as a [[sensor]] to track changes in [[natural frequency|frequency]] or [[phase shift|phase]] of the resonance of the fiber. One application is as a measurement device for [[dimensional metrology]].<ref>{{Cite journal | doi=10.1063/1.2052027|title = Development of a virtual probe tip with an application to high aspect ratio microscale features| journal=Review of Scientific Instruments| volume=76| issue=9| pages=095112–095112–8|year = 2005|last1 = Bauza|first1 = Marcin B.| last2=Hocken| first2=Robert J.| last3=Smith| first3=Stuart T.| last4=Woody| first4=Shane C.| bibcode=2005RScI...76i5112B}}</ref><ref>{{cite web|url=http://www.insitutec.com|title=Precision Engineering and Manufacturing Solutions – IST Precision|website=www.insitutec.com|access-date=28 April 2018|url-status=live|archive-url=https://web.archive.org/web/20160731063517/http://www.insitutec.com/|archive-date=31 July 2016}}</ref>
