CSEC Physics · January 2012 · Paper 2 · Question 6(b)(i)

In 2010, SONAR was used to detect submerged oil plumes. Figure 7 shows a ship using SONAR to locate an oil plume.

Explain, with reference to Figure 7, how SONAR was used to determine the depth of an oil plume.

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