Hey there,
Your question states: What factors affect the speed of water waves
Let's get one thing out the way, (wavelength) does [tex]NOT[/tex] affect the the speed of water. If anything, it would be how high the wavelength's are. The higher the wavelengths are, the more that it would affect the speed, because there very high, but if it were to go longer on the width side, that would increase the speed, but that's not the case. Your correct answer would be (higher wavelength).
Hope this really helps you.
