A long rope is stretched tightly between points A and B. Point A is caused to oscillate vertically, and a wave travels from A to B along the rope, as shown in Fig. 5.1. The time taken for one oscillation of point A is $0.20\,\text{s}$. During one oscillation, point A moves through a distance of $80\,\text{mm}$. The wavelength of the wave on the rope is $1.5\,\text{m}$.
(a(i))[1]
Explain what the term 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 whether the waves on the rope are progressive or stationary.
(c(ii))[1]
State and explain whether the waves on the rope are longitudinal or transverse.
