Two water waves meet at the same point,one having a displacement above equilibrium of 50 cm and the other having a displacement above equilibrium of 90 cm.At this moment,what is the resulting displacement above equilibrium?
A)140 cm
B)95 cm
C)40 cm
D)Information about the amplitudes needs to be given to find an answer.
E)65 cm

Question

Quizplus · Accepted Answer

When two waves meet, their displacements add together due to the principle of superposition. Therefore, the resulting displacement is 50 cm + 90 cm = 140 cm.
