Question
4.
A guitar string has a set of natural frequencies at which it vibrates. Each frequency in the set is
characterized by a standing wave pattern. The standing wave patterns for a guitar string are
characterized by the presence of nodes at the end of the string (where it is clamped down). Each
standing wave pattern (and its corresponding frequency) is called a harmonic. The first harmonic is
the lowest frequency in the set (sometimes termed the fundamental frequency), followed by the
second harmonic, third harmonic, etc. Draw the standing wave patterns for the first, second, and
third harmonics of a guitar string.
