We have already encountered such periodic motion in the
back-and-forth movement of pendulums and masses on a spring and with the cyclic
orbits of objects in a gravitational field. The physics of waves is also central
in explaining how light and sound work.
Anything from a violin string to a drum
skin to a wine glass can make a sound, suggesting that there are few things in
the world that cannot produce wave phenomena. We find waves in the air, in our
bodies, in earthquakes, in computers—and, if we’re surfers, at the beach.
