Speed of a Wave For example, an ocean wave is traveling in one direction has a wavelength of 1.0m and a frequency of 1.25Hz. What is the speed (in m/s) of this ocean wave? v wave f 1.25 m s Please note that the water is not actually moving at this speed, but the wave is propagating at this speed. If a cork were sitting on the water it would most likely just bob up and down.
Clicker Question 13A-1 In the previous example, if the source of the wave suddenly doubled its frequency how would the previous answer change? A) The velocity of the wave would quadruple. B) The velocity of the wave would double. C) The velocity of the wave would remain the same. D) The velocity of the wave would half. E) The velocity of the wave would decrease by a factor of four.
