CAPE Physics Unit 1 · 2016 · Paper 2 · Question 2(c)(i)

Table 2 shows how the wavelength produced on a stretched string changes as the wave speed is varied.

On the grid provided in Figure 4 (page 11), plot a suitable graph to respresent the data.

This question uses a figure or table from the paper — you'll see it when you practise.
