[QUOTE="Topper, post: 882740, member: 186250"] I do not know much in the way of practicalities on that VS, nor do I remember much on wave propogation theory but digging back into my brain from over 20 years ago, I suspect you would have to experiment considerably with lengths as from what I vaguely remember, standing waves would only be created under certain conditions when the length of the pipe was incorrect based upon the frequency being received and whether it was exactly a first 3rd or 5th harmonic TBH I just cannot remember and a quick google search reveals [URL='http:///www.google.co.uk/search?q=standing+waves+in+pipes&espv=2&es_sm=117&tbm=isch&tbo=u&source=univ&sa=X&ei=5nRJU6iBB_Dd7QbJooDQDg&ved=0CC0QsAQ&biw=1280&bih=840#facrc=_&imgdii=_&imgrc=nqnBw-l-SQL-FM%253A%3B8b4tA_PuNwAZUM%3Bhttp%253A%252F%252Fhedberg.web.cern.ch%252Fhedberg%252Fc%252Foscillation%252Fwaves_2.jpg%3Bhttp%253A%252F%252Fhedberg.web.cern.ch%252Fhedberg%252Fc%252Foscillation%252Foscillation_hl.htm%3B765%3B463']this[/URL] for an open pipe and [URL='https://www.google.co.uk/search?q=standing+waves+in+pipes&espv=2&es_sm=117&tbm=isch&tbo=u&source=univ&sa=X&ei=5nRJU6iBB_Dd7QbJooDQDg&ved=0CC0QsAQ&biw=1280&bih=840#facrc=_&imgdii=_&imgrc=UGjMwAbIwflamM%253A%3B8b4tA_PuNwAZUM%3Bhttp%253A%252F%252Fhedberg.web.cern.ch%252Fhedberg%252Fc%252Foscillation%252Fwaves_3.jpg%3Bhttp%253A%252F%252Fhedberg.web.cern.ch%252Fhedberg%252Fc%252Foscillation%252Foscillation_hl.htm%3B770%3B511']this[/URL] for a closed pipe but I doubt this will help you [/QUOTE]
