- A brass bell (B Fig 11) was
substituted for the tuning fork. The ribbon R was inserted also.
No sound from M.
- To test whether the difference of metals used in the last experiments had
anything to do with the result a piece of steel was substituted for the
brass ribbon R and the bell B was then rung.
No sound from M.
- Piece of steel substituted for B (Fig 9).
Sound as in Experiment 10.
(Thoughts.)
It seems as if the sound from M (Figs 7,8,9,10,11) was loudest when the metallic surface
B Fig 10 is largest and the
vibrating surface in contact with the water smallest.
Try the following arrangement. Fasten wire W to stretched membrane
m.
