What is the speed of a wave with a wavelength of 3 hz?

Ok so Consider an ocean wave with a wavelength of 3 meters and a frequency of 1 hertz. The speed of the wave is: Speed = 3 m x 1 wave/s = 3 m/s.If a wave has frequency, f, of 3 Hz, its period, T, is 13s . The wavelength, λ , is 5 meters. That means that in the time of one period, the wave travels 5 m. Note: the unit Hz is equivalent to what it was called 100 years ago

Explanation:

frequency or wavelenth of em radiation in a vacuum
