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

Another stretched string is used to form a stationary wave. A part of this wave at a particular instant is shown in Figure 3. The points on the string are at their maximum displacement.

State the phase difference in the motion of the points on the string labelled X and Y.
