Question 5
1 Work in groups. Stretch out a slinky (a spring toy) loosely on a horizontal surface. Fix or hold one end of the slinky steady (Figure 11.7, top).
2 Quickly compress and release a few coils at the other end. This will create a wave that travels along the length of the slinky (Figure 11.7, bottom).
3 How does this experiment show how a sound wave moves?
