Ocean waves are hitting a beach at a rate of 2.0 Hz. The distance between wave crests is 1.5 m. Calculate the speed of the waves.

3.0 m/s

Explanation:

Given;

Frequency f = 2.0 Hz

Wavelength λ = 1.5 m

The speed of a wave can be expressed as a function of its wavelength and frequency.

Wave speed = frequency * wavelength = fλ

Substituting the values;

Wave speed = 2.0Hz * 1.5m

Wave speed = 3.0 m/s
