Two water waves meet at the same point,one having a displacement above equilibrium of 60 cm and the other having a displacement above equilibrium of 80 cm.At this moment,what is the resulting displacement above equilibrium?
A)140 cm
B)100 cm
C)70 cm
D)Information about the amplitudes needs to be given to find an answer.
