Wavelength
The wavelength is the distance between repeating units of a
wave pattern. It is commonly designated by the Greek
letter lambda .
In a sine wave, the wavelength is the distance between the midpoints of the wave:
The
x axis represents distance, and
I would be some varying quantity at a given point in time as a function of
x, for instance sound pressure or strength of the
electric or
magnetic field for
light.
