Use the image to answer the question.
An illustration shows a sine wave on a screen. The sine wave oscillates between positive one and negative 2 vertically and between negative 4 and positive 4 horizontally. There are 4 peaks and 4 valleys visible within the graph on the screen.
How many complete wavelengths are shown in this image? Do not count any partial wavelengths.

Explanation: Each full wavelength goes from one peak to the next peak (or from one valley to the next). With 4 peaks visible there are 4 − 1 = 3 complete peak-to-peak cycles (equivalently 3 valley-to-valley cycles), so 3 complete wavelengths.
