CAPE Physics Unit 1 · 2008 · Paper 2 · Question 5(b)(ii)

With water of the depth used in the experiment, it can be shown that the speed of the ripples of wavelength less than 2.0 mm is given by v² = k/λ + c, where k and c are constants and v is measured in mm s⁻¹.

a) Take readings from the graph and draw a suitable table of values. b) Using the graph paper provided on the insert, plot a straight line graph to test the relationship. c) Use your graph to determine the value of k.

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