Question

A set of water waves travels at 10.0 m/s, and 5.0 waves pass you in 2.0 s. What is the wavelength of the waves?


0.2 m

0.25 m

4.0 m

5.0 m

Answer 1

haha
wave velocity: \(v=10\)m/s
frequency: \(f={5\over2}\)Hz

use the formula:
\(v=f\lambda\)

and obtain \(\lambda\)=wavelength

Answer 2

4.0m is the answer?

Answer 3

yes
