A standing sound wave is established in a tube that is closed at one end and open at the other end. The period of the wave is $T$ . The diagram represents the standing wave at $t = 0$ and at $t = \frac{T}{8}$ . The wavelength of the wave is 1.20 m. Positive displacements mean displacements to the right.

(d.iii)

Draw on the diagram the standing wave at time $t = \frac{T}{4}$ .
