Lapp, Claude Jerome · leaf 48
; first, the straight form of tube is perfectly symmet-rical, second, the energy was supplied in correct quantities, andthird, the energy was supplied in the proper place in respect tothe wave length. In each wave the energy was supplied at a point8.1 cm. from the node, while the distances to the… … X ■* 148 cm. 22 These waves from tube No.14, straight form, were taken underidentical conditions except that the energy for wave No. 58 was sup-plied by one burner, while the energy for No. 59 was supplied by two.Wave No.58 i3 a pure sine curve while the crests of 59 are flattenedIn addition, each…
