A transverse progressive wave is set up on a string. The graph shows the variation with time of displacement for a point on this string. [Figure 26.0] The separation XY on the graph represents the ......1.... of the wave. X and Y have equal ......2....... Which words correctly complete gaps 1 and 2?
This question uses a diagram from the original paper, which isn't shown here. Open the full paper from the past papers archive to see it.
A1: time period, 2: amplitudes
B1: time period, 2: displacements
C1: wavelength, 2: amplitudes
D1: wavelength, 2: displacements
✓ Correct answer
B: 1: time period, 2: displacements
