Interference – effect produced
by two waves passing simultaneously through a
region
1. Superposition – when waves overlap, the
resultant
displacement is the algebraic sum of the
individual displacements of each wave

Task
The diagram below shows two waves
traveling in the same medium. Points A ,
B , C , and D
are
located along the rest position of the medium. The waves interfere to
produce a resultant wave.
Rank the magnitude
of the displacement from the equilibrium position from greatest to
least. Ties Are Possible.
