A wave has a frequency of 900 Hz and a wavelength of 200 m. At what speed is this wave traveling?

The velocity of the wave is, v = 180,000 m/s

Explanation:

Given data,

The frequency of the wave, f = 900 Hz

The wavelength of the wave, λ = 200 m

The formula for the speed of the wave when the frequency and wavelength are known,

                               v = λ x f

Substituting the given values in the above equation,

                               v = 200 m x 900 Hz

                                v = 180000 m/s

Hence, the velocity of the wave is, v = 180,000 m/s
