# Speed and wavelength of water waves given distance

Water waves in a lake travel 4.4 m in 1.8s. The period of oscillation is 1.2 s.

a. What is the speed of water waves?

b. What is their wavelength?

#### Solution Preview

...

Velocity (V) = Distance traveled (D) / Time taken (T)

= 4.4 m / 1.8s = 2.4444 m/s

b) The water wave has the property of periodic motion.

The velocity for a periodic wave is given ...
