Standing Wave Worksheet
A wave that is confined in a space is called a standing wave. Standing waves
on the vibrating strings of a guitar produce the sounds you hear. Standing
waves are also present inside the chamber of a wind instrument.
I
A string that contains a standing wave is an oscillator. Like any oscillator, it
has natural frequencies. The lowest natural frequency is called the
fundamental. Other natural frequencies are called harmonics. The first five
harmonics of a standing wave on a string are shown to the right.

There are two main parts of a standing wave. The nodes are the points where
the string does not move at all. The antinodes are the places where the string
moves with the greatest amplitude.
Node
Antinode
The wavelength of a standing wave can be found by measuring the length of two of the "bumps" on the string.
The first harmonic only contains one bump, so the wavelength is twice the length of the individual bump.
