(i) mark the direction of movement of the student's hand,
Ξ Ξ Ξ
(ü) mark and label the wavelength of the wave,
(ii) mark and label the amplitude A of the wave.
(b) Describe how the frequency of the wave is found using a stopwatch.

(c) Using the same rope, the student produces a wave of a longer wavelength than that shown in
Fig. 4.1.
Slate how the student does this.
