Question

A wave has a wavelength of 3.3m and a speed of 5.6m/s. What is the frequency of this wave?

Answer 1

The frequency of a certain wave is the quotient obtained by dividing the speed of the wave by the wavelength. That is 

                                         f = s/λ

Substituting the known values,

                                         f = (5.6 m/s) / 3.3 m

                                            = 1.7/s

                                            = 1.7 Hz

Hope this helped!
