If a water wave vibrates up and down 26 times each second and the distance between water crests is 7.55 m, what is its wavelength?

Answer 1

In case distance between two successive crests is 7.55m , then this it self is wavelength.

Answer 2

So the answer is 7.55m

f = 26Hz

λ = 7.55m

λ is the wavelength, this is the same as the distance between crests of a wave.
