So a wavelength is the distance from one point on a wave to the next equivalent point. i.e. after a point the wave needs to go up (to a crest) and then down (to a trough) and then back to the starting point for a complete wavelength.

In the file, 10m is the length for 3 crests and 2 troughs. This is 2 whole waves, and one half a wave. So 2.5 wavelengths = 10m. So what would one wavelength be?
4. Is it 10m/2.5= 4 wavelengths ?
5. (Original post by hastudent)
Is it 10m/2.5= 4 wavelengths ?
Yes so the wavelength is 4m.
6. I understand it now. Thank you
