A taut rope is stretched between points A and B. Point A is driven vertically, sending a wave along the rope towards B, as shown in Fig. 5.1. The time for one complete oscillation of point A on the rope is $0.20\,\text{s}$. In one oscillation, point A travels a total distance of $80\,\text{mm}$. The wave on the rope has a wavelength of $1.5\,\text{m}$.
(a(i))[1]
Explain what displacement means for the wave on the rope.
(a(ii)1)[1]
Calculate, for the wave on the rope, the amplitude.
(a(ii)2)[3]
Calculate, for the wave on the rope, the speed.
(b)[2]
On Fig. 5.1, draw the wave pattern on the rope at a time $0.050\,\text{s}$ later than the one shown.
(c(i))[1]
State and explain if the waves on the rope are progressive or stationary.
(c(ii))[1]
State and explain if the waves on the rope are longitudinal or transverse.
Worked solution & mark scheme
This 9-mark question has a full step-by-step worked solution and mark scheme. One marking point: “displacement is the distance from the equilibrium/mean/rest position (not the total distance moved)” …
