{"product_id":"kundts-tube-e-for-sound-wave-experiments","title":"Kundt's Tube E - for sound wave experiments","description":"Product Information: ..\u003cbr\u003eThe Kundt’s tube equipment set consists of a transparent acrylic tube with a movable scale and two removable end caps with built-in hose nozzles for filling the tube with various gases. The column of air is excited by means of a built-in speaker, which can be driven using a function generator or pulse box K (item no.: 1017341). More accurate measurements can be made using the capillary disc in front of the speaker, because standing waves remain largely unaffected by the “soft” speaker membrane. Measurements of the time it takes sound to propagate (with the help of the pulse box) are carried out without the capillary disc. In order to vary the length of the column of air, the sensor disc can be screwed to the end of the long microphone probe.","brand":"3B Scientific","offers":[{"title":"Default Title","offer_id":49419140366613,"sku":"3BS1017339","price":966.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0857\/4897\/3845\/files\/U8498308_01_Kundts-Tube-E-for-sound-wave-experiments.jpg?v=1761029354","url":"https:\/\/unitedsupplycorp.com\/products\/kundts-tube-e-for-sound-wave-experiments","provider":"United Supply Corp.","version":"1.0","type":"link"}
