We first introduce some terminology
associated with waves. Let us imagine that we drop a rock in the
of a still pond and watch the waves emanating out from the center.
From above the wave crests might appear as in
We assume the wave pattern is regular, and consider the following characteristics of these waves.
T = .
f = .Using the expression for T above we get the useful expression:
v = f.
