Wavelength of a Wave

APPH12-8EKYLK

What is the wavelength of the wave shown? The x-axis shown is in units of meters.

Note: The graph could be describing any physical wave, such as an ocean wave moving up and down or a wave moving down a string causing the string to move up at down. The peaks shown in the graph may represent the string at its greatest positive amplitude and the troughs shown may represent a string at its greatest negative amplitude. The amplitude is the measured value between the mid-point (zero point on the y-axis) of the wave and the peak (or trough) on the y-axis.
