CSEC Physics · May/June 2006 · Paper 2 · Question 3(a)(i)

Figure 2 shows successive stages in the generation of a transverse wave on a stretched slinky spring.

Indicate on Figure 2F by appropriately labelling a) the position of a crest b) the position of a trough.

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

The mark scheme is shown once you've answered.
