The equipment set consists of a resonance tube with a millimetre scale which is partially filled with water and is connected to an expansion vessel with a tube. The column of air above the water is excited to oscillate by using a tuning fork (or optionally a loudspeaker). By raising the expansion tank, the level of water inside the tube can be raised as well, which therefore reduces the height of the air column. The sound wave emitted by a sound source above the one open end of the tube is superimposed on the wave reflected from the surface of the water which results in constructive or destructive interference. Audible resonances occur when the length of the oscillating column of air is an odd integer multiple of a quarter wavelength of the sound.\u003cbr\u003e\nHeight of resonance tube:          1 m\u003cbr\u003e\nDiameter of resonance tube:      3 cm\u003cbr\u003e\nScale:                                              98 cm\u003cbr\u003e\nDivisions:                                       1 mm\u003cbr\u003e\nHeight of expansion vessel:       24 cm\u003cbr\u003e\nDiameter of expansion vessel:   7 cm\u003cbr\u003e\nWeight (without accessories and stands):         3.3 kg approx.\u003cbr\u003e\u003cstrong\u003eContents:\u003c\/strong\u003e\u003cbr\u003e\n1 Resonance tube with scale\u003cbr\u003e\n1 Expansion vessel\u003cbr\u003e\n1 Silicone tube\u003cbr\u003e\n2 Horizontal clamps\u003cbr\u003e\n1 Standard tuning fork, a\u003csup\u003e1\u003c\/sup\u003e = 440 Hz\u003cbr\u003e\n1 Beater\u003cbr\u003e\n \u003cbr\u003e\n \u003cbr\u003e\n\u003cstrong\u003eExperiment \u003c\/strong\u003e\u003cstrong\u003eTopics\u003c\/strong\u003e\u003cstrong\u003e:\u003c\/strong\u003e\u003cbr\u003e\n·         Resonances in an oscillating column of air\u003cbr\u003e\n·         Standing sound waves\u003cbr\u003e\n·         Determination of wavelengths of sound waves in air\u003cbr\u003e\n·         Determination of speed of sound in air\u003cbr\u003e\u003cli\u003e\n\t\tSecure online payment with SSL\u003c\/li\u003e\n\t\u003cli\u003e\n\t\tExpert advice\u003c\/li\u003e\n\t\u003cli\u003e\n\t\tFinancing available\u003c\/li\u003e\n\t\u003cli\u003e\n\t\tEasy returns \u0026amp; exchanges\u003c\/li\u003e\n\t\u003cli\u003e\n\t\tInternational shipping available\u003c\/li\u003e\u003ch5\u003e\u003cspan\u003eSpecifications\u003c\/span\u003e\u003c\/h5\u003e\u003cul\u003e\n\u003cli\u003eUPC: Not Specified\u003c\/li\u003e\n\u003cli\u003eGTIN\/ITF Barcode: Not Specified\u003c\/li\u003e\n\u003cli\u003eUnits of Measure: Not Specified\u003c\/li\u003e\n\u003cli\u003eOverall Product Length: Not Specified in\u003c\/li\u003e\n\u003cli\u003eOverall Product Width: Not Specified in\u003c\/li\u003e\n\u003cli\u003eOverall Product Height: Not Specified in\u003c\/li\u003e\n\u003cli\u003eWeight Capacity: Not Specified lbs\u003c\/li\u003e\n\u003cli\u003eActual Product Weight: 3.31\u003c\/li\u003e\n\u003cli\u003eProduct Assembly: Not Specified\u003c\/li\u003e\n\u003cli\u003eProduct Installation: Not Specified\u003c\/li\u003e\n\u003cli\u003eCountry of Origin: Not Specified\u003c\/li\u003e\n\u003cli\u003eCase QTY: Not Specified\/case\u003c\/li\u003e\n\u003cli\u003eCase Weight: Not Specified\u003c\/li\u003e\n\u003cli\u003eShips Via Freight: Not Specified\u003c\/li\u003e\n\u003cli\u003eProposition 65 Warning: Not Specified\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3B Scientific","offers":[{"title":"Default Title","offer_id":48199080214720,"sku":"1018475","price":398.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1403\/8729\/files\/1776975883453.jpg?v=1776975886","url":"https:\/\/tensnet.com\/products\/quincke-s-resonance-tube","provider":"TENSnet","version":"1.0","type":"link"}
