Question

A succession of 2-m long water waves on a lake goes by a piece of floating cork that bobs up and down one complete cycle each second. What is the speed of the wave?

Answer 1

The speed of the wave is 2 m/s

Step-by-step explanation:

It is given that,

Distance covered by water waves or the wavelength of water wave,
`d=2\ m`

The water waves on a lake goes by a piece of floating cork that bobs up and down one complete cycle each second, t = 1 s

The speed of the wave is equal to the distance covered divided by total time taken i.e.

`v=(d)/(t)`

v = 2 m/s

So, the speed of the wave is 2 m/s. Hence, this is the required solution.
