Question

Ocean waves are hitting a beach at a rate of 3.5hz. What is the speed of the waves if the distance between wave crests is 1.3 meters?

Answer 1

`v=4.55 m/s`

Explanation:

The distance between wave crests is the wavelength: `1.3 m`
The frequency in Hz or `s^-1` is: `3.5 Hz`

`v= flambda`

`v= 1.3 m*3.5 s^-1`

`v=4.55 m/s`
